High-flux filter method of composite polyphase catalysis materials

Abstract

A flux screening process of combination heterogeneous catalysis material, wherein the multi-path reacting gas produced in the reaction furnace enters the multi-port valve of the mass spectrum detecting system through the capillary tube, which selects any path of the gas to enter the mass spectrum detector for analysis, each of the capillary tube is connected to each path of the multi-port valve through a six-way valve, and the six-way valve connects to a gas chromatograph simultaneously, the calculation of reaction conversion rate is realized through the comparison of the mass-spectrometric data of each path of reacting gas and margin reaction tube.

Description

technical field [0001] The invention relates to a combined method for rapidly screening heterogeneous catalysts. Background technique [0002] Combinatorial chemistry is a new method for the rapid synthesis of a large number of compounds developed in the past 20 years. Combinatorial chemical synthesis technology has brought revolutionary changes to traditional organic synthetic chemistry, and is another revolution in the history of organic synthesis, so it is called one of the important scientific achievements in recent years. [0003] Attempts at combinatorial methods are not new. In 1963, Merrifield reported solid-phase peptide synthesis, which earned him the Nobel Prize in Chemistry in 1984. In the 1980s, with the introduction of the concept of hybrid splitting by Furka and the optimization of the coding scheme for solid-phase synthesis by Geysen and Houghten, the concept of combination was greatly developed. These early works laid the groundwork for today's successful ...
