It can also be obtained by controlling the polymerization reaction of ethylene under the action of alkyl aluminum, and then obtain the heptadecene fraction through oxo synthesis.
18-alcohol is widely used in daily chemicals, textiles, printing and dyeing and other industries. raw materials for agents, emulsifiers and various additives. The specific uses are as follows:
