Isocyanates are a class of organic compounds.
Nature:
Isocyanate is a volatile liquid or solid substance, common phenyl isocyanate, methyl isocyanate and so on.
Purpose:
1, they can react with hydroxyl compounds to undergo addition reactions to form urea or uric acid derivatives.
2, isocyanate can also be used as an active compound to participate in organic synthesis reactions, such as the synthesis of polyurethane.
Preparation:
Methods for preparing isocyanates include reacting an amine with a corresponding anhydride or carbonate to produce an imide, and then reacting with carbon monoxide to produce an isocyanate. The corresponding isocyanate can also be obtained by reacting with sodium cyanide.
Safety information:
1, isocyanate has irritating odor and irritating effect, irritating effect on the skin and eyes, need to avoid direct contact.
2. Isocyanate is volatile, and a well-ventilated environment should be maintained during operation.
3, in storage, it should be sealed and stored away from fire sources and oxidants to prevent fire or explosion.

Physical and Chemical Properties |
generic name of various esters of isocyanic acid. Colorless clear liquid, with strong irritation. Monoisocyanate R-N = C = O and diisocyanate O = C = N-R-N = C = O. Generally a liquid with an unpleasant odor. One isocyanate is easy to react with ammonia or amine to form urea, and is easy to react with alcohol to form urethane (such as urethane). |
