A method is provided for producing glycol tert-butyl ether (GTBE). Diol and methyl tert-butyl ether (MTBE) are used. With the help of an acidic cationic exchange resin catalyst, GTBE are produced through transetherification. The present invention not only produces GTBE but also obtains highly-selective GTBE products. No by-products of glycol di-tert-butyl ether (GDtBE) and olefin are generated. The present invention effectively avoids the traditional complex procedure for separating GDtBE.

Method of Producing Diethylene-Glycol Tert-Butyl Ether Using Isobutylene and Diethylene Glycol
Usually an analysis of fuel displacement accident is required before operating a reactor. In the present invention, fuel displacement accident is analyzed by linearly combining calculation results of single displacement layouts and a calculation result of a default placement layout. In this way, a number of displacement combinations to be analyzed can be reduced. And, thus, time for the analysis is saved and safety of the reactor core can be affirmed.
