摘要
无磷洗涤剂是今后洗涤剂发展的必然趋势．然而作为洗涤剂中普遍使用的增洁剂三聚磷酸钠，由于其对环境水体造成严重污染．开发合适的替代物愈来愈为人们所重视，经过对５００多种新型增洁剂的筛选，认为４Ａ沸石是取代三聚磷酸钠的理想替代物．文章根据我国的现有状况，比较了几种生产４Ａ沸石的制作工艺．化学合成法应列为优先发展的方法．
Nonphosphoric detergent will be the inexorable trend of detergent exploitation in the future. But sodium terpolyphosphate was generally used as an adding cleaner in detergent industry, which was paid more attention, becouse the environment was polluted by the phosplate. 4A fluorite is thought to be an ideal succedaneum of sodium terpolyphosphate after screenning over five hundred kinds of new adding cleaner for exloiting proper succedaneum of the phosphate. According to domestic status, several proceeses of producing 4A fluorite were compare in the paper. We would give priority to the procees of chemical synthesis.
