Dicyclohexylamine
Dicyclohexylamine, CAS No. 101-83-7, is a semi colorless liquid with fishy smell.
Dicyclohexylamine has the chemical properties of secondary amine. It is strongly alkaline and can form salts with various acids. Acylation reaction may occur.
In terms of solubility, dicyclohexylamine is slightly soluble in cold water and almost insoluble in hot water. Miscible hand ethanol, ether and benzene.
Dicyclohexylamine is used to prepare dye intermediates, delayed rubber vulcanization accelerator OZ, nitrocellulose paint, insecticide enhancer, catalyst, preservative, vapor phase corrosion agent, fuel antioxidant additive, acid gas absorber, and steel rust inhibitor. It is widely used as an intermediate of organic synthesis and also as an extractant. Dicyclohexylamine fatty acid salt and sulfate have the detergency of soap, and are used in printing and dyeing and textile industry. Its metal complexes are used as catalysts for inks and paints.
O-chloroaniline
The English name of o-chloroaniline is o-chloroaniline, CAS No. 95-51-2, which is amber liquid with ammonia odor.
As there is chlorine substitution on the aromatic core of o-chloroaniline, the alkalinity of o-chloroaniline (25 ℃, pKa=2.636) is much weaker than that of aniline: (25C, pKa=4595). Its chemical properties are similar to that of aniline, and it can generate salts with inorganic acids, but the rate of acylation and diazotization reaction is slow. The color turns black when exposed to the air.
In terms of solubility, o-chloroaniline is insoluble in water and soluble in ethanol, ether and most organic solvents.
O-chloroaniline is used as dye intermediate, solvent, mildew inhibitor and reagent. This product is an ice dye color base, and can also be used as a diazo component of azo dyes to produce acid black, acid blue and organic lake water solid yellow R, Yonggu red FR, Hansha yellow HR, etc. It can be used to prepare cross-linking agent methyldichloroaniline for medicine, pesticide and polyurethane resin.
