Abstract

The invention discloses a preparation method of 6-amino-1-hexanol by taking calcium carbonate as a catalyst. Calcium carbonate serves as the catalyst of a reaction, 1,6-hexanediol, ammonia and hydrogen are mixed and react for 1.5-2 h in a heated and pressurized mode on the condition that the temperature ranges from 270 DEG C to 290 DEG C, and the pressure ranges from 150 Mpa to 180 Mpa, and 6-amino-1-hexanol is generated. According to the preparation method, calcium carbonate serves as the catalyst, the raw materials are easy to obtain, the cost is low, the catalytic efficiency is high, and the catalytic effect is stable; the finished product 6-amino-1-hexanol is high in purity and high in yield, the high economic benefit is achieved, and the preparation method can be widely applied and promoted.

Description

Technical field: [0001] The invention relates to a method for preparing 6-amino-1-hexanol using calcium carbonate as a catalyst. The method uses calcium carbonate as a catalyst. Background technique: [0002] 6-amino-1-hexanol, the English name is 6-amino-1-hexanol, the CAS number is 4048-33-3, the molecular formula is C6H16NO, it is white needle crystal at room temperature, the melting point is 58-60 °C, and the boiling point is 130.5-131.5 ℃, in a ventilated and dry place, sealed and stored, with irritation. 6-Amino-1-hexanol is a chemical intermediate, which contains hydroxyl and amino groups, and has the general properties of alcohols and amines. It can be used to prepare special organic chemicals, medicines and pesticides, and has a wide range of uses. [0003] my country's production technology for 6-amino-1-hexanol is relatively backward, and most of them rely on imports, which are expensive. [0004] At present, there are many methods for producing 6-amino-1-hexano...
