Background and Overview

N-butylamine products: a n-butylamine, two n-butylamine, three n-butylamine; N-butylamine is an important chemical raw material and intermediate for organic synthesis, which is widely used in industry, agriculture and medicine.

Main uses: n-butylamine: used as emulsifier, medicine, insecticide, rubber products, dye manufacturing intermediate products and chemical reagent. Di-n-butylamine: used as emulsifier, corrosion inhibitor, insecticide, rubber accelerator, polymer inhibitor, etc. Tri-n-butylamine: mainly used as a solvent, intermediate, insecticide, emulsifier and so on.

The n-butylamine formation reaction is a process in which the raw materials are synthesized in the reactor to produce n-butylamine, di-n-butylamine, tri-n-butylamine and water. Because after the reaction, a set of device to generate three products at the same time, the purpose is different, the market of three products is also different, lead to some product sales very good, some products unsalable phenomenon, although you can by controlling the ratio of raw materials and the reactor temperature to adjust the output ratio of products, but inevitably some unsalable products generated; The product sales and product inventory brought great pressure, serious may cause the problem of device shutdown, at the same time the best-selling products in short supply. One n-butylamine is also known as butylamine. Colorless volatile liquid. Molecular weight 73.14. Melting point - 49.1 ℃. Boiling point 77 ~ 78℃. Relative density 0.7414(20/4℃). The refractive index is 1.4031. It is miscible with water, alcohol and ether. It smells of ammonia. Flash point - 14 ℃.

The preparation of

A n-butylamine as a pharmaceutical intermediate, used in the production of anti-diabetic drugs; Pesticide intermediate, used for the production of carbamate herbicides; Auxiliaries intermediates, used for making cracked gasoline anti-glue agent, additives, gasoline antioxidant, rubber polymer inhibitor, siloxane elastomer vulcanizing agent, soap emulsifier. N-butylamine is also a color photographic developer. It is synthesized by butanol and ammonia under normal pressure. It can also be prepared by the reaction of butanol with ammonia via chlorobutane. Examples of its applications are:

1) Preparation of N-butyl thiophosphotriamine. The method used at certain temperatures, a n-butyl amine, inorganic sulfur aqueous alkali drops to the generation of phosphoryl chloride and organic solvent mixture, after the reaction, to separate water phase, with the warm, to the organic phase zhongtong into ammonia, detection reaction finished, filter removal of ammonium chloride, filtrate recycle most of the solvent, cooling, crystallization, filtering, drying for a quick end product NBPT. The method uses inorganic alkaline water solution as acid binding agent, which overcomes the shortcomings of complex and complicated recovery of organic alkali, and can directly separate and remove inorganic salts after the reaction. The raw materials are cheap and easy to obtain, the steps are simple, the product yield is high and purity is high, and it is suitable for industrial production.

2) Solve the cracking of silica film, and use its porous characteristics for adsorption and coloring. The porous SiO2 sol was prepared by adding water, anhydrous ethanol, n-butylamine and tetraethyl orthosilicate into the beaker in turn and controlling the stirring and adding time. The sol is put into the spray can and sprayed onto the glass substrate at a certain spraying speed; When the sol is completely gel, the glass substrate is immersed into the methylene blue solution, adsorption for a certain time, and the glass substrate is taken out. At this time, the film on the glass substrate is not cracked. At the same time, a large amount of methylene blue solution is adsorbed in the solution, so that the glass substrate is colored. The invention realizes that the glass substrate after spraying sol is immersed in methylene blue solution to solve the problem of cracking in the process of gel drying, and at the same time achieves the purpose of adsorbing organic dye to make glass coloring. This method can be applied to industrial production on a large scale.

3) Preparation of a modified waste rubber powder/natural rubber composite material, including the following steps: (1) the use of continuous microwave oven to microwave processing of waste rubber powder, the processing time for 20 to 60 seconds, (2) placed after microwave processing of waste rubber powder in 35-40 ℃ is ethyl silicate swelling in 1-3 days, then the waste rubber powder into a 35-40 ℃ 10% n-butyl amine solution treatment 1 day, remove a n-butyl amine solution, the waste rubber powder in vacuum oven 50 ℃ treatment 3-5 days, was prepared in situ generated silica modified waste rubber powder, the quality of this invention will waste rubber production with rubber products, reduce the production cost
