What are the processes for hydrogen cyanide? Is it easy to get approval for projects these days?
All environmental impact assessments for cyanides are approved by the **Ministry of Environmental Protection**

It depends on what products you plan to make using hydrocyanic acid; **if it is encouraged and supported, then approval will be granted easily
Highly toxic, flammable and explosive; for liquids, moisture must be controlled to prevent polymerization； There are companies with large production capacity for sodium cyanide.
For methanol ammonia oxidation, natural gas ammonia oxidation, and light oil cracking, the downstream products are generally reported directly. There are too many restrictions on the transportation of cyanides; currently, the trend is for downstream manufacturers to produce cyanides themselves, and any questions can be addressed via private message
Our company transfers the technology for producing sodium cyanide; using natural gas and ammonia as primary raw materials, an ANDRVSOW reactor is employed to generate HCN, which is then reacted with liquid alkali to produce NaCN
Are you producing now? Can you produce hydrocyanic acid? I possess advanced technology for the processing of hydrocyanic acid
I’ve heard that hydrogen cyanide is produced by using hydrocyanic acid, water, and sulfuric acid to create a 60% sulfuric acid solution; sodium cyanide is then added to this mixture. The resulting hydrogen cyanide is condensed and introduced into the reaction vessel. After that, direct steam is introduced into the bottom of the vessel to distill out the hydrogen cyanide, which is then used in the preparation of the next batch of sulfuric acid. Post-treatment in dilute sulfuric acid area.
Those involved in investment will do a rough estimate: Butadiene + 2HCN = HMDA; 54 + 54 = 108, and it then depends on the conversion rate. 11,000 tons of butadiene – how much will HCN cost? The HDMA nylon at the back will cost no less than 25,000, I guess supply has been interrupted recently. 50,000 tons each, that’s 100,000 tons in total. If no accidents occur and the factory operates steadily for 10 years, the sales volume will be 10X2.5X10 = 25 billion. In three years, there will also be 7.5 billion RMB. With 7.5 billion RMB, it’s possible to buy many things around the world and build large factories; the business prospects are very good. . . The richest people can afford to spend money. . . . . . . .
What about using glycolic acid downstream of HCN? Adiponitrile is obviously good, but what about water – is there any technology related to it? It’s all monopolized by foreign countries.
