| titleOfInvention | Two asparatate of a kind of N, N '-decanedioyl base and preparation method thereof |
| abstract | The invention discloses a kind of N, two asparatate of N ' decanedioyls base and preparation method thereof, it is characterized in that：Using water as solvent, asparatate carries out acid-base neutralization reaction with sodium hydroxide, produce Asparagus cochinchinensis ammonia acid sodium, in the presence of acid binding agent, sebacoyl chloride and Asparagus cochinchinensis ammonia acid sodium, substitution reaction is carried out in ice-water bath, generate N, two Asparagus cochinchinensis ammonia acid sodium of N ' decanedioyls base, reaction mass is diluted with water, it is slowly added to acid solution, adjust PH to 1.0 or so, solid product is precipitated, with water washed product repeatedly, obtain N, two asparatate of N ' decanedioyls base, synthetic is a kind of organic polycarboxylic acid, the characteristic combined with metal with multiple carboxyls, excellent anti-rust action can be played；Synthetic has the function of the stable comple formed with calcium and magnesium ion. |
