What is the easiest way to separate carbon dioxide?

Of course it is temperature separation.

The boiling point of carbon dioxide in the air is minus 56.6 degrees, while the oxygen reaches minus 183 degrees, and the nitrogen is minus 195.8 degrees.

As long as the temperature reaches minus 56.6 degrees Celsius, the first thing that is separated is carbon dioxide.

But the question is, where is Liu Mingqi looking for equipment to create an ultra-low temperature of tens of degrees below zero?

As for Fidel's method, arsenic alkali method, casul's method, etc., there is no way.

Liu Mingqi can only leave books and wait for decades to see if anyone can do such an experiment.

The lime method that Liu Mingqi uses now has many disadvantages, such as insufficient filtration, low purity of sugar, poor color, etc.

But it can be obtained everywhere and the process is simple. By comparing the advantages of white sugar by grasping the pH and temperature, all the disadvantages are not disadvantages.

Liu Mingqi is now preparing to write down the production process and finish the process by herself.

When Tian Rong gathers good people, he can start extracting white sugar by lime.

While busy here, Princess Yu arrived at his yard.

Dazhu reported to him that Liu Mingqi appeared in front of Princess Yu in a gray work robe and a mask.

"Ahem!"

The smell of lime in the room made Princess Yu feel uncomfortable, "Qi'er, what are you doing? Why do you make it like a dock servant?"

"Oh, I'm making a kind of refined sugar." Liu Mingqi took off her mask and said, "It's easier to preserve than brown sugar, and it's sweeter and better looking."

"This silly child, what's the use of eating so beautifully?" Princess Yu smiled and stepped forward to pat the lime on her son's body. Although she was coughing repeatedly, she did not stop.

However, Liu Mingqi was embarrassed, so she quickly took a few steps back and took a few slaps on her own. After the fog dissipated, she said, "Mom, you...oh, wait!"

He suddenly rushed back to his house, then ran back, handing him a large porcelain bottle to Princess Yu.

"What?" Princess Yu naturally would not be wary of her son. She took the opportunity to smell it, and as a result, a strong fragrance of plum blossoms came to her nose.

Looking at the slightly intoxicated mother and the two maids behind her, Liu Mingqi was very happy: "Mom, this is the plum blossom essential oil I made for you. You apply some on your face every day and let them massage you. It can protect your skin and replenish moisture. Your face will become whiter and tenderer, not much different from a teenage girl."

"hehe!"

Princess Yu gave her son a blank look, "When did you learn to be so slick?"

"This is the fact!" Liu Mingqi patted her chest and promised, "If you don't believe me, you will apply it a little sooner or later to ensure it is effective."

"That's good!"

Princess Yu smiled and handed the bottle of plum blossom essential oil that was filled with a pound to a maid behind her.

Then she said, "Qi'er, you are so old in the blink of an eye. Some things should be arranged for you for your mother."

While speaking, Princess Yu pointed to the maid on the right side behind her, "Qiaolian has been following me for five years, and her parents are also old people in our palace. From now on, she will stay by your side and be responsible for your daily life. Don't bully her!"

Princess Yu has many maids, including old mothers, personal butlers, and some are responsible for travel.

But there have always been only two maids in her close body.

If the previous one is married, it will be automatically made up.

Nowadays, one is called Qiaolian and the other is Luling.

Lu Ling is only sixteen years old this year, a little younger than Liu Mingqi, and looks pretty and cute.

Qiaolian is the one she assigned to Liu Mingqi. She is eighteen years old this year. She grew up in the royal palace and is well-nourished. She is at least 1.65 meters tall. Her beautiful eyes are dark and deep, her willow eyebrows are suitable for each other, her nose is tall, her face is a little pointed, and her expression is a bit light, and she has a bit of a domineering demeanor.

Princess Yu had told Qiao Lian before coming, so after Qiao Lian heard it, she did not have any unexpected expressions, but bowed her waist and said, "Your Highness, please forgive me if I have any bad things in the future!"

"Where are there." Liu Mingqi scratched her head, but felt a little embarrassed: "Mom, I am living a good life alone. Qiao Lian is a girl, is it a bit inconvenient to come here?"

"Silly kid!"

Princess Yu was both funny and angry, "Many of the other royal families have given birth to children now! You are the only one who is stupid, and you don't know how good women are!"

Liu Mingqi also felt ah in her heart.

Nonsense, why don't I know?

Back then, I was also from more than a thousand young ladies from all over the world on my hard drive!

Although I have never practiced it, even Kato Eagle is not necessarily better than me in various postures and techniques!

It’s just because I know a lot that I understand how terrible it is for a man to lose Yuanyang at the age of sixteen.

A man who indulged himself like this, without the help of Viagra, would at most become wet after he was in his thirties.

I, Liu Mingqi, was a senior magician in my previous life, but in this life, I dare not say that I have three thousand beauties, but I always want more than a dozen wives and concubines?

If you can't do it when you're in your thirties, then you're still going to be furious?

Therefore, I am now sleeping on firewood and tasting gall, and trying to defeat the young lady Sifang after leaving the sword in the future!

Unfortunately, I can't tell you this.

But then again.

It's still not possible to rely on Chi San and Dazhu's two generals.

They are only suitable for specific implementation, and women are more capable of careful arrangements and planning, inspections, etc.

Miss Qiaolian has been helping her mother with chores and has learned a lot of things, so she can be an assistant for me.

Besides, her parents and siblings are both servants of Prince Yu's mansion, so there is no need to worry about loyalty.

The boy, who was lonely with a hero, scratched his head, "Okay, thank you mother! Sister Qiaolian, don't worry, I won't bully you. You are my good brothers like Chi San and Dazhu."

"Puchi~~"

Lu Ling couldn't help laughing.

Princess Yu wanted to slap her son directly.

brother?

I can't beat you to death!

Qiaolian felt relieved when she heard this.

She was most afraid that she would become a man's forbidden body and could only please him, which would be too boring.

Now that the Crown Prince said this, he obviously has to take some responsibilities and assign some tasks to himself.

That's just right!

...

Princess Yu left, and Liu Mingqi looked at the beautiful young lady and didn't know what to say for a moment.

Qiao Lian smiled faintly, "Your Highness, where should I live? Please arrange it."

"Oh, I have many empty rooms here. Sister Qiaolian, you can just live there." Liu Mingqi said: "Let Dazhu ask someone to move all your things over later. If you have any needs, just go to the warehouse to get it."

"No one lives next to Your Highness's bedroom, right?" Qiao Lian asked.

"without."

"Okay, I'll live next door to you, so it's easier to take care of you!" Qiao Lian said.

"No need, I am such a big person, so how can you take care of me?" Liu Mingqi quickly refused, "Just help me take care of my small yard. If you have time, you can rest!"

Qiaolian smiled and did not refute him for the time being.

But she asked, "Your Highness was doing brown sugar just now, right? Can I go and have a look?"

"Yes!"

Liu Mingqi nodded and asked Dazhu, who was standing, to hand over a cloth mask, "Sister Qiaolian, put it on first."

"This is..." Qiao Lian was very smart and immediately woke up, "Is this to prevent dust?"

"Well, to be precise, it is to prevent lime powder." Liu Mingqi also put on the mask and led Qiaolian into his laboratory.

This room has been specially renovated and is similar to an ordinary modern laboratory.

As soon as Qiao Lian entered the door, she saw a huge copper cone half hanging in the air. It was sealed below. It was close to the top, but there were air outlets and two big ears.

At this moment, juice was flowing out of the two big ears and dripped into the wooden barrel below.

She has never seen anything like this.

Before she could ask, Liu Mingqi introduced: "This is a settlement device I commissioned to make for craftsmen. The material is cooked copper, which should be able to withstand corrosion for more than half a year. We just need to adjust the temperature and neutralize the pH and alkalinity, and then we can separate the clean juice and mud juice through this settlement device.

Then filter the mud juice to obtain the filtered juice. Mix the filtered juice and the clean juice, and you can use multiple evaporation to remove impurities and get snow-white sugar."

Qiao Lian thought she was a smart person.

But after hearing Liu Mingqi's explanations, she felt that she was listening to the heavenly books and didn't understand what it meant at all.

But she can still grasp the core point, "Have you made sugar now?"

"Not yet." Liu Mingqi said, "It took the craftsmen ten days to make this settler. Now I am doing the first step of separation experiment. If you want to get snow-white sugar, you have to wait at least tomorrow or the day after tomorrow."

In Qiao Lian's understanding, the sugar was yellow or red, and she had never thought about the snow-white candy, let alone seen it.
