応用分野
用途LiBH 4の製造
使用Source of hydrogen, reducing agent for aldehydes, ketones, acid chlorides; foaming agent for plasticsPotassium borohydride is used as a selective reducing agent for ketones, aldehydes and acid chlorides. It is used as a precursor in the production of chloramphenicol, vitamin A, thiopenicol, atropine and scopolamine. It is used to prepare high dispersive copper nanoparticles by the chemical reduction method using potassium borohydride as a reducing agent.
一般的な説明Potassium borohydride is a white crystalline or powdered solid. When exposed to water Potassium borohydride may react violently and start a fire. Potassium borohydride is toxic by ingestion. Potassium borohydride is used to make other chemicals.
調製方法
純化方法Crystallise it from liquid ammonia. It is slowly hydrolysed by H2O. Its solubility at ~20o in H2O or liquid NH3 is 20%, in MeOH it is 0.7%, in Me2NCHO it is 15% and in MeOH/H2O (1:4) it is 13%. [Jons & Wallbridge Progr Inorg Chem 11 99-231 1970.]
