In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 870-24-6, name is 2-Chloroethanamine hydrochloride belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 870-24-6
In a 500 ml four-necked flask,343 parts of dimethylformamide,31.6 parts of triethylamine and 2-chloroethylamine hydrochloride(Manufactured by Tokyo Chemical Industry Co., Ltd.) 33.2 parts, and the mixture was stirred for 10 minutes. 49.6 parts of p-toluenesulfonyl chloride (manufactured by Tokyo Chemical Industry Co., Ltd.)Was added little by little so that the liquid temperature did not exceed 20 C.,And the mixture was stirred at room temperature for 3 hours.The reaction solution was poured into cooled 5% aqueous hydrochloric acid,After stirring for 15 minutes, the precipitated crystals were collected by filtration, washed,By drying,33.8 parts of a dye intermediate represented by the following formula (101) was obtained.
The synthetic route of 870-24-6 has been constantly updated, and we look forward to future research findings.
