ammonium citrate tribasic purified 99.5%

Ammonium citrate dibasic is also named diammonium citrate or ammonium hydrogen citrate.It is a dibasic salt of citric acid and produced by complete neutralisation of citric acid with high purity ammonium hydroxide.It occurs as white colorless crystals. It is freely soluble in water with non-toxic.The PH value of ammonium citrate dibasic is often during 4.5 to 5.5 . And it easily deliquesces so that it should be kept in dry and airtight container .

 

 

   Ammonium citrate dibasic is mainly used as analysis reagent,buffer agent and textile           

   plasticizer material.It can be widely used in electronic capacitor industry also.Especially it

   can obviously improve performances of starch size film and adhesion of pure cotton yarn 

as a good textile auxiliary .
