Abstract: OLEFINS, SUCH AS C5 TO C30 ALPHA OLEFINS FORMED BY THERMAL CRACKING OF LONG CHAIN NORAML PARAFFINS, ARE SUBJECTED TO SOLVENT EXTRACTION TREATMENT BY CONTACTING THE OLEFINS IN LIQUID PHASE AT A TEMPERATURE OF ABOUT 50* TO BOUT 350*F., PREFERABLY, FORM ABOUT 65* TO BOUT 275*F., WITH AN ALKYLENE GLYCOL OR CYCLOALKYLENE GLYCOL SUCH AS ETHYLENE GLYCOL, 1,2-CYCLOHEXYLENE GLYCOL, ETC. THE THUS-TREATED ALPHA OLEFINS WHICH ARE LOW IN CONJUGATED POLYENES, I.E., DIENES, ARE HIGHLY USEFUL FOR PRODUCTION OF OLEFIN SULFONATE DETERGENTS HAVING AN IMPROVED COLOR.

Abstract: Olefins, such as C5 to C30 olefins formed by thermal cracking of long chain normal paraffins, are subjected to acid treatment by contacting the olefins in liquid phase at a temperature of about 0* to about 225*F. and, preferably, from about 50* to about 100*F., with an adsorbent supported sulfuric acid composition. The process can be conducted, for example, by passing the olefin in liquid phase through a bed of free-flowing, granular, solid adsorbent supported sulfuric acid composition prepared, for example, by contacting an adsorbent, such as silica gel, with sulfuric acid. The spent treating composition can be conveniently reclaimed by burning off the accumulation of adsorbed materials or through solvent action and the recovered silica gel reused in preparing an additional amount of the silica gel supported sulfuric acid material. The acid treated olefins are highly useful for production of olefin sulfonate detergents having an improved color.
Abstract translation: 通过使长链正链烷烃的热裂解形成的烯烃，例如通过长链正构链烷烃的热裂解形成的C5至C30烯烃，通过使液相中的烯烃在约0至约225°F的温度下接触进行酸处理，优选约50 DEG至约100°F，用吸附剂负载的硫酸组合物。 该方法可以例如通过将液相中的烯烃通过例如通过使诸如硅胶的吸附剂与硫酸接触而制备的自由流动的，颗粒状，固体吸附剂负载型硫酸组合物的床 。 废处理组合物可以通过烧掉吸附材料的积累或通过溶剂作用方便地回收，并且回收的硅胶重新用于制备另外量的硅胶负载的硫酸材料。 酸处理的烯烃对于生产具有改进颜色的烯烃磺酸盐洗涤剂非常有用。
