Chapter 287 Preparing the Soap Factory

7days ago Xuanhuan Novels 9
Western border, border town.

The washing stones purchased from Yinguang City filled four ships, and it took several days to unload them alone.

Now that there are sufficient raw materials, the soap production plan is officially put on the agenda.

The supporting factories and warehouses have been set up. The soap factory is located next to the industrial park, next to the No. 2 steam assembly factory, and the shape is exactly the same.

The roof, beams, columns and wall panels are all made of wooden structures, with a circle smaller size. In addition, the witch is responsible for the wood cutting and hoisting work, so the construction period only took only one week.

Using detergent stone, that is, natural alkali, to make soap is essentially a series of chemical reactions.

The required raw materials are also very common. In addition to soda ash, a large amount of lime milk and grease are also required.

Among them, lime milk is the suspension that precipitates at the bottom of the container after immersing lime in water. It is used to react with soda ash to form caustic soda, and then react with oil to form high-grade fatty acid salts and glycerol.

The former is soap, while the latter is an extremely important raw material for explosives.

When making soap, Roland had already tried a complete reaction process in the castle backyard.

The principles are basically the same, but to expand the small amount of trial production into mass production, reasonable processes and specifications are still needed. More importantly, professional chemical talents are needed to guide production.

To this end, he summoned the chief alchemist into the office.

Your Highness, I have come up with a plan that may be possible to produce sulfuric acid on a large scale.As soon as she entered the door, Kemoslier shouted, but this required a lot of lead, and the blacksmith who made the lead into a container. I heard that someone in your witch could accurately cut metal. The rumbling iron lumps were made by her. Can I...

Of course, if you give me the shape and size of the container you requested, I will ask the Witch Alliance to do it. Roland waved to him and sat down. I am not here to make acid today, but another task.

Your Highness, I really can't take time to do anything else recently. Kaimo shook his head and said, "Massive acid production is a difficult challenge, and I must do my best."He paused and added, "The disciples are not good either. They are all assisting me in preparing for this matter, and none of them can leave."

Don't worry, it won't take too much time for you. Roland took a sip of tea and didn't need to adjust your proud disciples to take charge. It only takes a few apprentices.

Then... what is the mission?

Making soap is a cheap version of soap in the convenience market. In addition to its taste, its function is exactly the same as that of soap. It can be used for bathing, cleaning clothes, and cleaning tableware.

Is it the saponification reaction mentioned in "Elementary Chemistry"?Kaimo touched his beard and said, "Which one that reacts with sodium hydroxide and oil to produce alcohol and salt?"

It has to be said that it is a very strange feeling to hear standard chemical nouns from an alchemist, especially this word is created by oneself.

Roland held back his smile and nodded seriously, "Yes, it's the saponification reaction recorded in ancient books."I also found out how to make soap based on it.

So what do you need me to do?If it is not very important, I recommend putting it in the future before production.After all, it would be fine if your subordinates didn’t take a bath for several days. Just soak your clothes, meal plates, etc. directly in the river.

It is very important, the prince stressed, or rather, it is not important to make soap, but the by-products in the production process are something I need at the moment.

You mean... alcohol?Kaimo said disapprovingly.

That's right, it's alcohol, you can also call it glycerin.Roland said that it is an extremely important raw material and its significance is no less than two acids.

OK, Kemostrile shrugged, but I agreed that I don’t have time to implement it myself.

He exhaled gently, it was really tiring to deal with the chief alchemist. You just need to pick out a few clever apprentices and demonstrate it in front of them.I will recruit some leaders to produce, but they know nothing about chemistry after all, so someone must check all aspects.The prince paused for a moment, and you could also treat it as a chemical experiment that had never been practiced before. If placed in an alchemy workshop, this process could mean the discovery of several alchemy formulas, enough to allow an apprentice to receive the title of alchemist.

It was probably the last sentence that convinced Kaimo. If that was the case, I would take an afternoon to teach the content you assigned to the apprentice.

Very good, Roland smiled slightly, you should also know that the most important thing in the production process is to produce enough sodium hydroxide. He wrote the reaction formula on paper. Before the synthesis alkali process was invented, natural alkali was the most important alkali-making raw material. The latter's main ingredient was sodium bicarbonate. Heated it can be decomposed into sodium carbonate, carbon dioxide and water. Because the raw materials are rich and the process is simple, it is still used until modern times.

Heat the detergent stone, decompose, dissolve water, and filter, and obtain a purer sodium carbonate solution.

Next, use it to coheate with lime milk to obtain a sodium hydroxide solution. You should easily think of the purification method. He explained while writing, clarify, distillate, mix, and repeat this step until the solution concentration can precipitate a large amount of crystallization after cooling.

These are all the contents involved in "Elementary Chemistry". Because the two alkalis have many nicknames, they are very easy to be confused (such as caustic soda, caustic soda, soda, baking soda, soda, etc.), and are also important knowledge points in the exam. He had memorized a lot of relevant content in the textbook at the beginning, so he still remembers them clearly.

I understand. The chief alchemist looked at the reaction from beginning to end, but Your Highness, what should I do with grease?

I will arrange for someone to send these materials to you.Animal oils were still expensive in this era, but after the last time the seed procurement journey of Qinwei brought olive tree seeds from Zhulongling, Bianfeng Town had a reliable source of vegetable oil.

Although it is currently only planted in the backyard of the castle, it is not a problem to harvest a bunch of fruits a day with the ability to ripen leaves.

The extraction of olive oil is also very simple. After the fruit is ripe, it can produce oil by using physical cold pressing. Then filter out the debris and residue through a filter to obtain clear oil.

Finally, after briefly explaining the requirements for soap preparation and glycerol retention, Roland asked Kemospier to leave the office.

In this way, when the soap factory started construction, he had a stable channel to obtain glycerol.

And with glycerol, it means that the real smokeless launching drug and powerful explosives are also not far from him.
