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 (C₃)x, (C₄)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.
