Properties and stability
This product has an ammonia smell and a bitter taste. It is irritating to the skin and has low toxicity. Wear protective masks and gloves during production and application. Rinse with plenty of water after accidental contact.
Storage method
Flammable liquids should be stored in a sealed container, placed in a ventilated and cool place, away from fire and heat sources, and transported in a fireproof manner.
Synthesis method
1. Prepared from cyclohexylamine as raw material.
2. From cyclohexanone and Derived from the reaction of methylamine. Soak the aluminum sheet in methanol, add high mercury chloride, and continue soaking for 2 hours. The temperature does not exceed 55°C, and the soaking liquid is removed. Add ethanol to the above-mentioned activated aluminum flakes, add a mixture of methylamine and cyclohexanone dropwise under stirring, heat to reflux, and leave overnight. Add 10% sodium hydroxide solution to alkalize, extract twice with benzene, wash with water and then distill. After benzene is recovered, N-methylcyclohexylamine is distilled off. The yield is about 80%.
Purpose
Drug and dye intermediates. Used as an intermediate for the drug hexylamine bromide hydrochloride.
