This invention relates to processes for making biodegradable surfactant. The process comprises several steps including an optional step. The first step is directed to reacting olefins with ZSM-23 catalyst to form oligomers having the formula -(C.sub.3).sub.x, (C.sub.4).sub.x or mixtures thereof. Second, the oligomer is hydroformylated to form a saturated alcohol, for example, tridecanol. Next, the saturated alcohol is ethoxylated. Thereafter a nonionic biodegradable surfactant is recovered. This surfactant can be used in detergent formulations. A process is also taught for making esters which can be used as lubricants or plasticizers. A specific hydroformylation process is taught which utilizes modified cobalt carbonyl catalyst. Also, a specific ethoxylation process is taught. Products formed according to the latter two processes as well as their uses are also taught.
本发明涉及制备可生物降解表面活性剂的过程。该过程包括多个步骤,包括一个可选步骤。第一步是将烯烃与ZSM-23催化剂反应,形成具有式-(C.sub.3).sub.x,(C.sub.4).sub.x或其混合物的寡聚体。其次,对寡聚体进行氢甲酰化反应,形成饱和醇,例如十三醇。接下来,对饱和醇进行乙氧基化反应。然后,回收非离子型可生物降解表面活性剂。该表面活性剂可用于洗涤剂配方中。还教授了一种制备酯类的方法,可用作润滑剂或增塑剂。还教授了一种利用改性钴羰基催化剂的特定氢甲酰化反应过程。还教授了一种特定的乙氧基化反应过程。还教授了根据后两种过程形成的产品及其用途。
