据有关资料报道,目前我国可生产约1600种各类工业表面活性剂,总产量为700kt/a左右,可满足国内需求的80％。 (1)离子表面活性剂 80年代后期,我国阳离子表面活性剂像雨后春笋般蓬勃发展,虽然生产规模不大,但品种很多。目前全国有阳离子表面活性剂的生产企业300多家,总能力在100kt/a以上,但实际年产量不足20kt。LAS、SES是阴离子表面活性剂中产量最大的两种产品,占阴离子表面活性剂的 According to relevant data, at present, China can produce about 1600 kinds of various types of industrial surfactants, with a total output of about 700kt/a, which can meet 80% of domestic demand. (1) Ionic surfactants In the late 1980s, China’s cationic surfactants flourished like bamboo shoots. Although the scale of production is small, there are many varieties. At present, there are more than 300 cationic surfactant manufacturers in the country with a total capacity of over 100kt/a, but the actual annual production is less than 20kt. LAS and SES are the two largest products of anionic surfactants, accounting for anionic surfactants
