Method for continuously preparing 3, 3, 3-trifluoro-2-(trifluoromethyl)-1-propylene in gas phase

The invention discloses a method for continuously preparing 3, 3, 3-trifluoro-2-(trifluoromethyl)-1-propylene in a gas phase, and the method comprises the following steps: by taking octafluoroisobutylene as a raw material, carrying out hydrogenation-dehydrofluorination-hydrogenation-dehydrofluorination four-step gas phase continuous reaction to obtain the 3, 3, 3-trifluoro-2-(trifluoromethyl)-1-propylene. The hydrogenation catalyst and the dehydrofluorination catalyst have the characteristics of high activity and long service life; according to the present invention, by using the gas phase independent circulation process, the incomplete reaction material is subjected to independent circulation so as to completely convert the initial raw material into the 3, 3, 3-trifluoro-2-(trifluoromethyl)-1-propylene, and finally the product 3, 3, 3-trifluoro-2-(trifluoromethyl)-1-propylene is efficiently and continuously and circularly extracted from the process system in the gas phase; therefore, liquid waste and waste gas are not generated, and green production is realized.

A six-fluorine different butylene synthetic method (by machine translation)

The invention discloses a six fluorine different butylene synthetic method, comprises the following steps: (1) will be heptafluoro isobutylene methyl ether and borohydride in the I-type solvent in the reaction, after the reaction filter, and get the hexafluoro-isobutylene methyl ether; (2) the step (1) the obtained hexafluoro-isobutylene methyl ether with acid reaction, after the reaction and get the six fluorine different butyraldehyde; (3) under the action of catalyst, to the step (2) in the butanal obtained six fluorine different hydrogen by the reaction of, after the reaction and filtering to obtain the hexafluoro-isobutyl alcohol; (4) the step (3) the obtained hexafluoro-isobutyl alcohol and alkali reaction in II-type solvent, collecting the reaction product and get the hexafluoro-isobutene product. The invention has simple technique, high yield, the operation is simple, and low cost. (by machine translation)

Preparation method of hexafluoroisobutene

The invention discloses a preparation method of hexafluoroisobutene. The method comprises the following steps of (a) reacting isobutylene dimethyl ether, benzylhemiformal and halide in an I-type solvent, carrying out rectification to obtain benzopyloxane; (2) reacting the benzopyloxane obtained in the step (1) under the action of a catalyst, filtering and rectifying filtrate to obtain hexafluoro-isobutyrate; (3) reacting the benzopyloxane obtained in the step (1) and a chlorination agent in an II-type solvent, adding water for layering and rectifying an organic layer to obtain hexafluorisobutyrate chloride; and (4) reacting the hexafluorisobutyrate chloride obtained in the step (3) and an organic alkali, condensing and collecting a reaction product to obtain the hexafluoroisobutene. The method has the advantages of being few in three wastes, high in yield, simple in operation and low in cost.
