Dodecylamine,1-Aminododecane, Laurylamine - Preparation Method
Open Data Verified Data
using lauric acid as a raw material, ammonia gas was introduced in the presence of silica gel catalyst for ammoniation, and the reaction product was washed with water, dried, and distilled under reduced pressure to obtain refined lauric nitrile. The lauronitrile was transferred into an autoclave, heated to 80 ° C. By stirring in the presence of an active nickel catalyst, repeatedly hydrogenated and reduced to obtain crude laurylamine, which was then cooled and subjected to distillation under reduced pressure to obtain a finished product after drying.

| Introduction | dodecylprimary amines, also known as 1-aminododecane, laurylamine, dodecylamine, colorless or white crystals. This product is weak alkaline, and inorganic acid or organic acid can generate salt. Quaternary ammonium salt may be used. With the epoxy ring reaction, can be acetylated. With unsaturated hydrocarbons can be added. Peroxide can be used to oxidize this product. The reaction with a halogenated carboxylic acid produces an amphoteric compound. Reaction with carboxylic acid chloride, can produce amide. The Mannish reaction with the nucleophile or phenol can be carried out to produce a polyfunctional species. With hydrochloric acid, the formation of hydrochloric acid dodecylamine. |
| Application | dodecylprimary amine is an important intermediate for the synthesis of cationic and zwitterionic surfactants, which is widely used in mineral flotation agent, fiber waterproof softener, dyeing auxiliaries, antistatic agents, pigment dispersants, anti-rust agents, chemical fertilizer anti-caking agents, lubricating oil additives, sterilization disinfectants, etc. |
| toxicological data | 1. Skin/eye irritation: rabbit skin standard Drez-eye test: 750ug/24h has serious irritation to the skin. Rabbit eye standard Drez-eye test: 50ug/24h had severe eye irritation. 2. Acute toxicity: Rat oral LD5O:1020mg/kg; Mouse oral LD5O:1160mg/kg; Mouse peritoneal LD5O:50mg/kg |
| purpose | for the preparation of surfactants, mineral flotation agents, dodecyl quaternary ammonium salts, fungicides, pesticides, emulsifiers, detergent and other organic synthesis intermediates, used in textile and rubber and other additives production. It can also be used to prepare Ore flotation agent, dodecyl quaternary ammonium salt, bactericide, insecticide, emulsifier, detergent and Disinfection special effect agent for prevention and treatment of skin burn and curing. used as an active agent in geological analysis and also in chromatographic analysis organic synthesis. |
| production method | with lauric acid as raw material, ammonia gas is introduced into the reaction in the presence of silica gel as catalyst, and the product is washed with water, dried, distillation under reduced pressure gave lauronitrile. Lauronitrile is hydrogenated under active nickel catalysis, I .e., it is reduced to give dodecylamine. Lauronitrile was added to the autoclave, and an appropriate amount of active nickel was added to replace the room air with nitrogen. The mixture was heated to 80 ° C. With stirring, and hydrogen charging was repeated until absorption was no longer observed, and the reaction was maintained for 3 hours. After cooling, the obtained crude product was subjected to distillation under reduced pressure to obtain dodecylamine. |
