A new technique is provided for the production of folacin by adjusting the temperature,the pH value,the feedstocks and the equipment.The technique raises the production efficiency of folacin,lowers the consumption of raw materials,meliorates the product quality,reforms the operating conditions,manages pollution of environment and at the same time makes the continuous production possible.
甲酸钙(Calcium Formate),分子式Ca(HCOO)2,分子量为130.0,外观为白色或微黄色粉末或结晶,无毒,味微苦,不溶于醇,溶于水,水溶液呈中性.甲酸钙的溶解度随温度升高变化不大,在0℃时16g/100g水,100℃时18.4g/100g水,400℃加热分解.
过氧化钙是一种新型的多功能无机精细化工产品,常温下是白色或淡黄色粉末,无臭、无毒,难溶于水,不溶于乙醇、丙酮等有机溶剂.在室温干燥条件下稳定,在湿空气或吸水过程中逐渐分解出氧气,其有效氧含量22.2%.加热至300℃开始分解,400~425℃全部分解成O2和CaO.过氧化钙不仅对紫外线有较强的吸收作用,还具有较强的脱色、杀菌、消毒、防腐、增氧等功能.
