过去曾关注其毒性问题,现住消费稳定增长。日本有日本乳化剂、四日市合成两家公司生产,1997年产量1200吨。生产方法采用乙二胺和环氧乙烷路线。日本从美国UCC、BASF、阿克苏诺贝尔等进口300吨,总消费1500吨。日本消费以表面活性制原料为主,占1/2以上,主要是咪唑啉型阳离子表面活性剂,用于香波和柔软剂。在两性表面活性剂方面,主要作柔软剂和防静电剂。见外,该品还有以下用途: 1、将氨基进行羧化后用作金属离子螯合剂。 2、消洗剂:硬币清洗,防止变褐。 3、润滑油添加剂:可直接或与甲基丙烯酸其聚物一起作防腐蚀剂和油污分散剂。 4、各种树脂原料:如用于水性乳液涂料,纸
In the past, it had paid attention to its toxic problems and the current consumption has steadily increased. Japan has Japanese emulsifiers and Yokkaichi synthesis of two companies. In 1997, it produced 1,200 tons. The production method uses ethylenediamine and ethylene oxide routes. Japan imports 300 tons of UCC, BASF, and Akzo Nobel from the United States, with a total consumption of 1,500 tons. Japan’s consumption of surfactant-based raw materials, accounting for more than 1/2, mainly imidazoline cationic surfactants for shampoo and softener. In terms of amphoteric surfactants, softeners and antistatic agents are mainly used. See also, the product has the following uses: 1, the amino carboxylation used as a metal ion chelator. 2. Detergent: Coin cleaning to prevent browning. 3, lubricating oil additives: can be used directly or together with methacrylic acid as corrosion inhibitor and oil dispersant. 4, a variety of resin materials: such as water-based emulsion paint, paper
