Abstract
Description
Claims (3)
- 염화크롬(CrCl3· xH2O), 황산크롬(Cr2(SO4)3· xH2O) 또는 질산크롬(Cr(NO3)3· xH2O) 중에서 선택된 +3가 크롬의 강산염과 같은 당량의 피콜린산을 물에 녹여 80-100℃에서 20분 이상 가열한 후, 이 반응에서 생성가능한 산의 전량을 중화하는데 필요한 알칼리의 50-100%를 반응액의 pH가 1.5 내지 3.5가 유지되는 범위에서 반응액에 서서히 가한 후 계속 70-100℃에서 20분 이상 가열하는 것으로 되는 피콜린산크롬의 제조방법.
- 제1항에 있어서, 알칼리가 수산화나트륨, 수산화칼륨, 탄산나트륨, 탄산칼륨, 산성탄산나트륨, 및 산성탄산칼륨 중에서 선택되는 것이 특징인 피콜린산크롬의 제조방법.
- 제1항에 있어서, 생성가능한 산의 전량을 중화하는데 필요한 알칼리의 50-100%를, 한번에 또는 수차례로 나누어 반응액에 첨가하여 중화처리하는 것이 특징인 피콜린산크롬의 제조방법.
