Release that Witch

331. The key to the art of Chapter 331

    “Church is like a sudden pop.”

    Until returning to the office, Roland still echoed this sentence.

    He closed his eyes and searched for Fourth Prince’s memory and still couldn’t find more. He knows about Church’s, just like ordinary noble – in the palace, Fourth Prince didn’t spend much time learning knowledge, and occultism was almost blank. But if Tilly is true, then Church’s promotion strategy is too strange.

    Taking the original religious legends of the world as an analogy, the gods originated from the beginning of the world is the pediatrics, the world is the creation of the gods is the routine that everyone chooses. For example, creation on the 7th, karma reincarnation, etc…A complete set of legends describing the power of God is a standard for every religion.

    Compared to Church in this world, it looks quite…Young and tender.

    However, Roland didn’t have more clues to continue his research. He shook his head and decided to leave these thoughts behind.

    Maybe after you have explored the ancient ruins of Hidden Forest, everything will have an answer.

    He walked to the window and looked at the huge coating on the ground in the garden – in the snow of the white, its green appearance was particularly eye-catching.

    Now that Soraya is bonding a larger air bag, the new hot air balloon will be even bigger and can carry more people. This is because if you can’t find a way to save the trapped woman when exploring ruins, simply let Anna chop the entire “ice” and bring her back to Border Town along with a portion of the transparent crystal stone.

    The set off time is set after two days.

    The staff has made arrangements for the Sleeping Island witch with Tilly, Silvy, Shavi, Ash and Andrea. Witch Union will send Anna, Wendy, Nightingale, Nana, Lightning, Macy. This lineup is unprecedentedly powerful, with attack, defense and battlefield perceptions reaching their highest level. Devil has a hard time getting close to them without using God Punishment Stone.

    “His Royal Highness, chief alchemist Cam Schuire wants to see you,” personal guard said outside the door.

    “Let him come in.”

    Cam didn’t come alone this time. He also brought his own colleague James. “His Royal Highness, the large-scale nitric acid method you requested, has a clue.”

    For real?”Roland glimpsed a little, and then a burst of joy came to mind. This is probably the best news I have heard in recent days. He stood up excitedly and personally gave the two chemists a cup of tea. “Quickly say, how was it made?”

    “This is James’s credit,” he said with a smile on his beard. “Let him come and explain it to you.”

    “Esteemed’s Highness,” the young James looked a bit cautious. He said after he was praying, “Your alchemical workshop…No, the chemical laboratory produces nitric acid, which is obtained by dry distillation of saltpeter to obtain dilute nitric acid, and then purified by concentrated sulfuric acid. I tried to put the two together and directly heated the saltpeter in concentrated sulfuric acid. As a result, the nitric acid solution was successfully obtained, and the purity was very high. Even the smoke phenomenon recorded in «Elementary Chemistry» was observed. ”

    “Together? But the two are not the same thing,” Roland wonders. “The temperature of the dry distillation is much higher than the co-heating, and the gas that is distilled off should be nitrogen oxides, which form dilute nitric acid when it is introduced into the water. The purification of concentrated sulfuric acid is simply to use the principle of high boiling point and strong water absorption to reduce the water content in nitric acid, and does not involve chemical reactions. ”

    “I don’t quite understand why, but Mr. Schuire did several experiments and thought that my discovery was a coincidence.”

    “Coincidence?”Roland looks to the chief alchemist.

    “It’s true,” Cam said. “The two are not the same, but they produce the same effect. I followed the chemical formula, guessing that this should be a component of the saltpeter that reacted with sulfuric acid to produce nitric acid and evaporate on heating. According to the formula, it looks like something…Well, nitrate. ”

    Roland suddenly remembered it in his mind. As mentioned in the chemistry textbook, before the artificial ammonia was invented, sodium nitrate or potassium nitrate was reacted with concentrated sulfuric acid to produce nitric acid, which is the oldest industrial process. Because the main component of saltpeter is two kinds of nitrates, it is convenient and easy to obtain, and it is easy to extract. As long as the temperature is controlled, the evaporated nitric acid can be collected continuously.

    Of course, because this method consumes a large amount of sulfuric acid and is extremely susceptible to corrosion, it was quickly eliminated by more advanced technology.

    However, these two points are not too big a problem for Roland. The fertilizer and pesticide industry has not been established in the territory. The sulfuric acid produced is only for the purification of nitric acid. As for the strong corrosiveness of nitric acid vapor, it can be given to Soraya’s coating solution.

    “Good job,” Roland patted James on the shoulders with delight. “This method can be tried out by you.”

    “You have no idea that he has shown extraordinary luck in scarlet Water City Alchemical Workshop,” Cam Schuire, “before learning chemistry, alchemy itself is a quest for luck, and this kid can At the age of 10, the two-acid method was developed to become the youngest alchemist in the workshop, and a bunch of thirty or forty-year-old apprentices were envious of their eyes. Be aware that they will be just an apprentice for the rest of their lives. ”

    “In any case, this is good news for small town,” Roland praised. “You try to make a batch of equipment to see, I will let the witch match you. If feasible, expand production scale. ”

    “As you wish.”

    “Right, I have another task to hand over to you,” and he put away the joy of joy, saying in a solemn tone, “Now that there is a reliable source of nitric acid, then I need you to try it out as dangerous. Item – Nitrification * Glycerin.”

    “How dangerous is it?”Cam asked.

    “The raw materials used are very simple, that is, concentrated nitric acid reacts with glycerin and is catalyzed by concentrated sulfuric acid, but the temperature must be strictly controlled during the reaction and kept ventilated. Since a large amount of heat is generated during nitrification, you can place the container in ice water for testing. Remember, cold, heat, vibration, impact, and friction can cause it to explode. ”Roland doesn’t know if these amateur knowledge is unreliable, but the ingredients are undoubtedly correct, and even if there is danger, they must try. “Just use a small amount of acid in the test, so even if an accident occurs, Miss Nana can rescue you. ”

    “This…”James opened his mouth and had not had time to answer. Cam had promised it. “I understand, its power is compared with snow powder?”

    “The weather is far away.”

    “It seems to be an interesting experiment.”Chief alchemist laughed.

    Nine of the ten chemists are potential explosive art lovers, and this is true.Roland thought.

    Nitrification* Glycerol is extremely unstable, and Nobel Bale’s safe explosives are in which the diatomaceous earth is encapsulated by the diatomaceous earth, which improves safety and reduces the explosive power. Roland naturally does not use this classical method. He intends to join nitrocellulose or nitrated starch in nitrification* glycerol, both of which can stabilize and further enhance the explosion. The former is an excellent smoke-free emission* drug, while the latter is a powerful and powerful explosive. As can be seen from their names, a large amount of nitric acid is the key to the evolution from black gunpowder to chemical gunpowder.

    And he now has this key.
