Abstract


In this paper, the fusel oil generated in the process of fermentation production of alcohol separation . Uses a high efficiency packing , for the the fusel oil after the pretreatment is performed twice precision distillation to obtain a high - purity 2 - methyl-1 - butanol and ( S ) - ( - ) -2 - methyl-1 - D alcohol. High 1.5m, diameter 150mm distillation column , batch distillation fusel oil pilot test to obtain a purity of greater than 98% of a mixture of amyl alcohol . Pentanol mixture in high- 1.6m the inner diameter 20rnm the fractionator precision distillation , concentration of raw materials , evaporation rate , the reflux ratio and other factors on the effect of separation , create a salting - precision fine evaporated separation system , the results show that : the raw material 2 - methyl-1 - butanol concentration of 60% of 2 - methyl-1 - butanol concentration in more than 99% , the highest yield was 82.7% (mass percentage ) or more, and further increased with the increase of the concentration of the raw material . Although the higher the reflux ratio and the lower evaporation rate is also conducive to the separation of the product , but the time and energy consumption will increase . Also studied wherein spin -pentanol ( i.e. ( S ) - ( - ) -2 - methyl-1 - butanol ) changes discovery procedure exists a certain degree of ( R ) - ( ) isomer to the ( S ) - ( - ) isomer conversion phenomenon is more obvious, and under the high concentration of material to obtain ( S ) - ( - ) the spin- pentanol optical purity more than 98% .
