Abstract

The invention discloses an analysis method for a reaction product of linear alpha-olefin prepared by ethylene oligomerization, which comprises the following steps: respectively feeding the reaction product of linear alpha-olefin prepared by ethylene oligomerization into a gas chromatograph-mass spectrometer and a gas chromatograph; the method comprises the following steps: by taking a ratio of a C18 linear alpha-olefin peak area in a gas chromatograph chromatogram to a C18 linear alpha-olefin peak area in a gas chromatograph chromatogram as a conversion coefficient, multiplying the peak area of a C20-C36 component with an even carbon number by the conversion coefficient to obtain a converted peak area of the C20-C36 component with the even carbon number; and finally, calculating the content of C4-C36 components with even carbon numbers through an area normalization method. The method is accurate, rapid, simple, convenient and reliable, and has important significance for production control and product quality control of linear alpha-olefin prepared by ethylene oligomerization.

Description

technical field [0001] The invention relates to the technical field of chemical analysis, in particular to an analysis method for preparing a linear alpha-olefin reaction product by ethylene oligomerization. Background technique [0002] Linear alpha-olefin (LAO) usually refers to high-carbon linear terminal olefins of C4 and above, including 1-butene, 1-hexene, 1-octene, 1-decene, 1-dodecene (carbon) Olefin and higher carbon number products are an important organic chemical raw material and intermediate, which are widely used in the synthesis of advanced lubricating base oil, lubricating oil additive synthesis, olefin comonomer, detergent, emulsifier, flotation agents, adhesives, etc. [0003] There are currently three routes for the preparation of linear α-olefins: (1) ethylene oligomerization; (2) CO / H 2 Fischer-Tropsch synthesis; (3) wax cracking of olefins. Among them, the preparation of linear α-olefin by ethylene oligomerization takes ethylene as raw material, and ...
