| titleOfInvention | Preparation of olefinic alcohols and borates |
| abstract | The invention comprises olefinic borate esters of the formula (RO)3B in which R1 is an olefinic radical of 6 to 30 carbons and to which the oxygen is connected at the carbon atom alpha to the double bond. Olefinic borate esters are made by forming a mixture of boric acid or boric anhydride and an olefinic hydrocarbon containing 6 to 30 carbon atoms per molecule, oxidizing said mixture in the liquid phase by contacting it with an oxygen-containing gas introduced at a rate of from 0.4 litre to 50 litres per hour, expressed in terms of oxygen content, at a temperature of 60 DEG to 190 DEG C. and for a period of 4 hours to 160 hours, and separating an olefinic borate ester. The olefine may be open chain or cyclic, many examples being given. When operating at temperatures near or above the boiling point of the olefine, superatmospheric pressures are used to maintain the liquid phase. The olefinic borate ester may be hydrolyzed to the corresponding unsaturated ester by heating with water, if desired with addition of a mineral acid. Typical conditions are between 50 and 100 DEG C. for between 10 minutes and 1 hour. In examples (1) tri(cyclohexenyl)borate is made and hydrolysed to 2-cyclohexenol and bis (3-hydroxy -2- cyclohexenyl) ether; (2) mixed borate esters are obtained from dodecene-1 and then hydrolysed; (3) a mixture of 2-ethylhexene -1 and boric acid is oxidized and the product hydrolysed to a mixture of isomeric olefinic alcohols; (4) an isomeric mixture of alcohols of a -pinene is similarly produced. Specification 944,110 is referred to. |
