  The invention relates to a method for formulation of a synthetic gas oil or an additive for gas oil in which an alkyl-aromatic compound or a mixture of alkyl-aromatic compounds is selected based on at least one parameter that is selected from the group that consists of the number of cycles of the aromatic core, the number of alkyl chains that are grafted to the aromatic cycle, the length of the alkyl chain or chains, the position of the aromatic cycle or cycles on the alkyl chain or chains of said alkyl-aromatic compound or compounds such that the cetane number of the synthetic gas oil or the additive for gas oil is greater than 30. The invention also relates to a process for the production of alkyl-aromatic compounds for use as a gas oil or additive.

  该发明涉及一种合成气油或气油添加剂的配方方法，其中基于至少选择自芳香核心的环数、嫁接到芳香环的烷基链的数量、烷基链的长度、芳香环在烷基链上的位置等参数中选择烷基芳香化合物或烷基芳香化合物混合物，使得合成气油或气油添加剂的十六烷值大于30。该发明还涉及一种用作气油或添加剂的烷基芳香化合物的生产工艺。

  Solid H3PW12O40 catalyzed the alkylation of p-xylene with 2-methylpropene to t-butyl-p-xylene with 75%-selectivity, while the selectivity with H2SO4 was only 7%. The selectivity of heteropolyacids tended to increase with the acid strength.
