Fowls egg protein and method for catalytic oxidation of alcohol by solid supported metalloporphyrin thereof

Abstract

The invention provides a method for catalyzing and oxidizing ethanol through poultry egg protein and solid-supported metalloporphyrin thereof. The method comprises the following steps: a poultry egg protein colloidal solution is stirred to be uniform in system and then dried, so as to obtain a poultry egg protein catalyst; a benzene solution dissolved with metalloporphyrin is dripped to the poultry egg protein colloidal solution, is stirred to be uniform in system and then dried to obtain a poultry egg protein metalloporphyrin catalyst; the prepared catalyst and ethanol are put into a high-pressure reaction kettle according to the mass ratio of between 2.9 and 0.3 to 158, and are introduced with air with the airflow rate of 0.04m<3> / h so as to react for 2 to 4.0 hours at the stirring rate of between 200 and 600 r / min, at a temperature of between 130 and 150 DEG C, under the pressure of between 0.8 and 1.2 MPa; and then the ethanol is catalyzed and oxidized so as to generate acetaldehyde and acetic acid. The catalyst prepared by use of the method contains no toxic heavy metal and causes no waste fluid polluting environment.

Description

technical field [0001] The invention relates to a preparation method of solid poultry egg protein and its immobilized metal porphyrin, and uses these materials as a catalyst to catalyze and oxidize ethanol to selectively generate acetaldehyde and acetic acid. Background technique [0002] Oxidation of alcohols to aldehyde or ketone compounds is one of the most desired functional group transformations in organic synthesis. Although a series of methods related to the oxidation of alcohols to aldehydes or ketones have been obtained. However, the research and development of a new environmental protection method and technology is still very much concerned by production companies. Because the currently used alcohol oxidation method is difficult to adapt to the needs of continuous development of green environmental protection. The main disadvantage of these oxidation methods is the generation of large amounts of toxic waste liquids. Using biomimetic catalytic materials, such as ...
