摘要
本文研究了以米糠饼为原料，稀盐酸为提取液，用石灰乳和氢氧化销中和沉淀制取植酸盐，并分别以稀盐酸溶解经过离子交换柱和草酸溶解、沉淀两种方法制取植酸。该法操作简便，原料易得，是一种可行的制取植酸的方法。
The preparation of phytic acid salt from rice bran raw stuff and diluted chlorhydirc acidextract solution with lime emulsion and sodium hydroxide neutralizing precipitation wasstudied in this paper. Two methods were used by diluted ehlorhydirc acid dissolve throughthe ionic exchange column and oxalic acid dissolve and precipitation preparaed phytic acid.This was a practicability method of phytic acid preparation with operation simplicity and rawstuff obtainable easily.
