    Abstract

    An automated on-line gas chromatographic method was developed for accurate kinetic studies of the catalytic synthesis of methyl tert.-butyl ether from methanol and 2-methylpropene. It includes a pressurized liquid injection valve than can be used for the direct introduction of liquified mixtures. The influence of the pressure and density of the sample mixture is discussed and the theoretical predictions are compared with the experimental results. The relative standard deviation of the results was to be better than 0.1% for the integrated peak area of 2-methylpropene (n = 6). The pressurized injection technique also offers good possibilities for capillary gas chromatography
