Embodiment Construction

[0013] Tetradecaldehyde preparation device of the present invention comprises the main reactor 1 that reaction raw material is used, the wiped film evaporator 2 that is connected with main reactor 1 pipeline, the rectifying still 3 that is communicated with wiped film evaporator 2 pipelines, and rectifying still 3 Still still 3 pipes are connected to the product collection tank 4. Ionone, methyl chloroacetate, and sodium methoxide are placed in the main reactor 1, and the three are reacted. In order to improve the heat exchange effect of the raw materials in the main reactor 1, an inner tank with brine is provided in the main reactor 1. The coil pipe 5 and the two ends of the inner coil pipe 5 protruding from the main reactor 1 are cooling water inlet 6 and cooling water outlet 7 respectively. The heat generated during the reaction is exchanged in time by using the brine in the inner coil 5 to ensure the orderly progress of the reaction.

Abstract

The invention discloses a preparation device for myristyl alcdehyde, which comprises a main reaction kettle used by reaction raw materials, a thin-film evaporator connected with the main reaction kettle, a rectifying still communicated with a thin-film evaporator pipeline, and a finished product collection tank connected with a rectifying still pipeline, wherein Beta-ionone, methyl chloroacetate, and sodium methylate are placed in the main reaction kettle. The device is characterized in that an inner coil pipe is arranged in the main reaction kettle; two end parts, reaching out of the main reaction kettle, of two ends of the inner coil pipe are a cooling water inlet and a cooling water outlet respectively. Through the adoption of the cooling manner of the structure, the inner coil pipe is arranged inside the main reaction kettle, and cooling water is supplied to the inner coil pipe; therefore, the temperature of the raw materials in the center of the main reaction kettle is allowed to be lowered by adopting the method for cooling down from the inside.

Description

technical field [0001] The invention relates to a tetradecaldehyde preparation device, in particular to a tetradecaldehyde preparation device with good cooling effect. Background technique [0002] As a blind drug, vitamin A acetate has the functions of maintaining normal visual function, maintaining the health of epithelial tissue cells, promoting the synthesis of immunoglobulin, maintaining normal growth and development of bones, promoting growth and reproduction, inhibiting tumor growth, and nutritional supplements. Tetradecaldehyde is as the intermediate of vitamin A acetate, and the quality of its preparation quality has determined the quality of the vitamin A acetate that obtains. At present, in the preparation process of tetradecaldehyde, the raw materials in the main reactor are cooled by cooling water through the jacket, but the cooling effect of the raw materials in the center of the main reactor is not good in this way, and it is difficult to obtain fourteen carbo...
