  • Patent number: 9988329
    Abstract: A transfer-hydrogenation process for preparing a carbonyl compound and an alcohol compound comprises the steps of (a) contacting a first carbonyl compound with a first alcohol compound in the presence of a transfer-hydrogenation catalyst in a first reaction zone at conditions effective to form a second carbonyl compound from the first alcohol compound and a second alcohol compound from the first carbonyl compound, and (b) removing the second carbonyl compound from the first reaction zone during step (a). The first carbonyl compound is a saturated aldehyde or ketone, or an ?,?-unsaturated aldehyde or ketone. The first alcohol compound is a primary or secondary alcohol. The second alcohol compound is ?,?-saturated. The transfer-hydrogenation catalyst includes a Group 8 to 11 metal. This process is useful for preparing and higher value alcohols, such as butanol or 2-ethylhexanol, from the corresponding carbonyl compounds by engaging lower alcohol (C2-C4) feedstocks instead of hydrogen (H2).

  • Publication number: 20180105673
    Abstract: A plasticizer has been identified that improves compatibility in PVC formulations where secondary plasticizers and viscosity modifiers are present. In general, 1,2- or 1,4-dialkyl cyclohexane dicarboxylate plasticizers exhibit poor compatibility, as evidenced by increased exudation, in the presence of secondary plasticizers, i.e. chlorinated paraffins and hydrocarbon-based viscosity modifiers. We have found that bis 1,4-(2-ethylhexyl) cyclohexane dicarboxylate (DOCH) displays the opposite behavior, showing greater compatibility in the presence of these compounds than most other 1,2- or 1,4-dialkyl cyclohexane dicarboxylate derivatives (i.e. DINCH) or blends of fast-fuser/general purpose plasticizers.
