By means of molecular designing, a series of sodium branched-alkyl benzene sulfonates weresynthesized through seven process, involving Frieded-Crafts reaction, Grignard reaction, sulfonationand neutralization. Those isomers have similar structure, carbons of same quantity, but the position ofalkylaryl dissimilarity. Liner fat acid, metaxylene and halogenated hydrocarbon of different carbonnumber were used as the starting materials. Optimum processing condition was confirmed consideringinfluence of a series of reaction factors such as feed proportioning, quantity of catalysts, quantitysolvent, reaction time, temperature and pressure. Eight kinds of isomers of sodium hexadecylxylolsulfonates were finally synthesized, and characterized by FT-IR.

目前焦化三苯在工业上使用范围小，销售价格也低于石油三苯。其主要原因是硫、噻吩等杂质含量高、气味重。而现在国际、国内焦化三苯、汽油、柴油等产品脱硫提纯去杂质的工艺均采用高压催化加氢法处理，该工艺设备投资巨大。根据以上情况我公司经多方联系，现已从国外大量购进ZX-10系列脱硫催化剂，用本催化剂技术已能将焦化三苯所含的硫化合物、氮化合物、不饱和化合物及很多杂质，臭味等脱除，处理后的三苯总硫含量低于石油苯，气味、颜色，均与石油苯一致。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
