Paragraph 0030; 0034; 0038; 0042; 0046; 0050; 0054; 0058, (2020/08/18)
The invention relates to the technical field of organic chemical synthesis. The method comprises the following steps: reacting hydrocyanic acid with formaldehyde to obtain a hydroxyacetonitrile aqueous solution, reacting hydroxyacetonitrile with ammonia to obtain an aminoacetonitrile aqueous solution, reacting aminoacetonitrile with hydrogen chloride, and concentrating, crystallizing, filtering and drying the obtained feed liquid to obtain aminoacetonitrile hydrochloride. The method provided by the invention is simple in technological process and mild in reaction condition, high-temperature and high-pressure operation is not involved, and used equipment is conventional equipment; except hydrocyanic acid, other raw materials are easy to obtain, and the raw material cost is low; waste waterand waste gas are small in amount and can be used indiscriminately, and only a small amount of ammonium chloride is generated; the product quality is good, and the appearance and content are higher than those of a sodium cyanide process.

-
Paragraph 0153; 0154; 0155; 0160; 0161, (2018/05/07)
The invention relates to a manufacturing method of nitrile. Compared with the prior art, the manufacturing method has the characteristics of significantly reduced using amount of an ammonia source, low environmental pressure, low energy consumption, low production cost, high purity and yield of a nitrile product and the like, and nitrile with a more complex structure can be obtained. The invention also relates to a method for manufacturing corresponding amine from nitrile.
