Evafanol AS-1 - Preparation Method
Open Data Verified Data
- hexamethylene diamine reacts with carbon dioxide in chlorobenzene solution to form hexamethylene diamine formate, and phosgene is introduced at low temperature to produce hexamethylene diaminecarbonyl chloride, hexamethylene 1,6-= isocyanate is produced by decomposition of hexamethylene chloride at high temperature, and HC1 gas is released. The reaction solution was cooled, filtered, and the solvent Chlorobenzene was distilled off under reduced pressure, followed by distillation under reduced pressure to obtain a finished product.
- using adipic acid by-product adipic acid hydrochloride and phosgene to react in the solvent chlorobenzene to generate hexamethylene -1,6-isocyanate, and then by distillation to remove the solvent and vacuum fractionation to obtain the finished product.

Evafanol AS-1 - Use
HDI is the most important monomer in aliphatic diisocyanate (ADI), accounting for about 60% of the total demand for ADI. Most HDI is prepared into HDI biuret or HDI trimer. HDI and HDI biuret and trimer are important raw materials for the production of polyurethane coatings and polyurethane elastomers. Polyurethane coatings produced from HDI, HDI biuret or trimer have the characteristics of non-yellowing and strong weather resistance, and are widely used in aviation, automobiles, construction, wood, plastics, leather, etc. This product is also used as a raw material for dry alkyd resin crosslinking agent and synthetic fiber
Used as a raw material for the production of polyurethane coatings, and also used as a raw material for dry alkyd resin crosslinking agents and synthetic fibers
It is used to produce fatty polyurethane coatings, and can also be used as dry alkyd resin crosslinking agent and leather finishing agent.

Evafanol AS-1 - Preparation
1. hexamethylene diamine reacts with carbon dioxide or hydrochloric acid to form hexamethylene diamine carbonate or hydrochloride, then photochemical reaction, then distillation to remove the solution, and distillation to obtain HDI. HDI reacts with water and catalyst to synthesize HDI biuret, then evaporates through a thin film evaporator to remove residual HDI, and adds a fibrillolytic agent to prepare a solution with 75% solid content to obtain HDI biuret as a raw material for high-grade paint. Each ton of product consumes about 1280kg of diamine (95%) and 4700kg of phosgene.
2. The adipic acid by-product adipic acid hydrochloride and phosgene are reacted in the solvent chlorobenzene to generate hexamethylene -1, 6-diisocyanate, which is then distilled to desolvate and fractionated under reduced pressure to obtain the finished product.
