FORFARANDE FOR PARTIELL HYDRERING OCH SVAVELREDUKTION AV TALLHARTS |
摘要 |
Partial hydrogenation and sulfur reduction of tall oil rosin process is disclosed whereby the olefinic double bonds of the tall oil rosin resin acid mixture are selectively hydrogenated without reduction of the dehydroabietic acid aromatic double bonds by contacting the tall oil rosin with hydrogen in the presence of a palladium on carbon catalyst under conditions of pressure and temperature to produce a partially hydrogenated tall oil rosin of reduced sulfur content and an acid number no lower than 160. |
