Annual transfer of 2000 tons of diphosphorus industrial technology transfer

Share Last update:2018-11-19 16:32

Product Name:Bisphosphane

CAS No.:5994-61-6


Paper surface technology + factory guidance:Specific price


Technology Details


Cooperation mode:Transfer or cooperative production

Market price:Glyphosate intermediate, very large domestic and foreign markets

Route of Synthesis:This product is currently diallyzed with diacetonitrile to form sodium diacetate salt, which is synthesized into the hydrochloride salt of disodium salt by acidification, then added with formaldehyde, added with phosphorus trichloride, and heated to reflux to complete the condensation. Finally, the pH value is adjusted by adding a liquid base, so that Shuanglanlin is precipitated in a crystalline form, and is purified by pressure filtration to obtain a product.

Equipment needed:咱 No relevant equipment is provided, and all large production materials can be provided after cooperation.

Wastes:Large amount of wastewater

More information

The synthesis process of glyphosate mainly consists of three processes of hydrolysis, condensation and purification. First, the raw material diacetonitrile and liquid alkali are added to a jacketed hydrolysis kettle for hydrolysis, and hydrolyzed to form a disodium salt. Steam was introduced into the jacket and the hydrolysis temperature was 80 °C. The ammonia evaporated from the hydrolysis tank is cooled and sent to an ammonia absorption tower, which is absorbed by water to form a dilute aqueous ammonia solution. When the concentration of the diluted ammonia water is 20%, it is pumped to the tank area, and the diluted ammonia water is periodically purchased by the user. The disodium salt is transferred to the condensation vessel, and formaldehyde, phosphorus trichloride, water and a catalyst are added to the condensation vessel, and the reaction temperature is 120 ° C, and the condensation reaction produces glyphosate. After the glyphosate was crystallized by cooling, the crude glyphosate was separated by a crude centrifuge, and the crude glyphosate was sent to a glyphosate refining kettle. The purified glyphosate is separated into a drying workshop after being separated by a refining centrifuge, and dried to obtain a product of glyphosate.
