    摘要: Organic by-products having higher boiling points than cyclohexanone (usually obtained from the bottoms of a distillation operation to separate cyclohexanone from other reaction products during cyclohexanone production) can be converted to recoverable cyclohexanone and cyclohexanol using a catalyst having high aluminum oxide concentrations. The preferred catalyst is one which has an aluminum oxide (Al2O3) content of at least about 95 wt. %, and more preferably greater than about 99 wt. %.

    摘要: Solids that, untreated, have a tendency to cake are treated with distillation bottoms that are liquid at about 60.degree. C. or less and are obtained from production of an alcohol having the formula:R2-R1-OH,wherein R1 is substituted or unsubstituted, branched, straight chain or cyclic, C.sub.4 to C.sub.12 and R2 is OH or H.

    摘要: A process for increasing the amount of isolatable products in a by-product stream generated in the production of 1,6 hexanediol includes combining the by-product stream with water to form a combination of the water and the by-product stream; and reacting the combination at a temperature between about 250.degree. C. to about 400.degree. C. at a pressure from about 1,000 psig to about 3,000 psig to form one or more reaction products.
