ABSORPTION PROCESSES OF N-BUTENES IN SULFURIC-ACID .1. DETERMINATION OF DI-SEC-BUTYL SULFATE, DI-SEC-BUTYL ETHER, AND SEC-BUTYL ALCOHOL BY HIGH-RESOLUTION GAS-CHROMATOGRAPHY

The n-butene derivatives, di-sec-butyl sulfate, di-sec-butyl ether, an d sec-butyl alcohol, ordinarily present in the process of olefin absor ption in sulfuric acid solutions, were determined by high-resolution g as chromatography (HRGC) with SE-54 as the liquid phase and flame ioni zation detection. The application of this chromatographic procedure is very important to the study of industrial catalytic processes which i nvolves absorption stages as in the alkylation of isoparaffins with n- butenes in the indirect acid hydration to sec-butyl alcohol.
