Abstract
The invention provides an environmentally-friendly process apparatus for synthesizing furanone. The apparatus comprises a reactor, a hydrogen recovery device, a zinc recovery device, a zinc acetate recovery device and a distilled water reusing tank, the top end of the reactor is connected with the hydrogen recovery device through a pipeline, the bottom of the reactor is connected with the zinc recovery device through a pipeline, the zinc recovery device comprises a filter tank, an activation tank and a drying tank, the bottom of the filter tank is connected with a concentrative evaporation kettle through a pipeline, and a material recovery port is arranged at the bottom of the concentrative evaporation kettle and is connected with the zinc acetate recovery tank through a pipeline. The hydrogen recovery device is arranged, so hydrogen generated along with the hydrogen recovery device is recovered, and potential safety hazards are reduced. Zinc powder is recovered through the zinc recovery device, is activated through the activation tank and is dried through the drying tank, so recycling of the zinc powder is achieved. Zinc acetate generated by a reaction is recovered through the zinc acetate recovery device, and distilled water is collected through the distilled water reusing tank. Pollution is reduced and eliminated from the source, and recycling of resources is achieved.
Description
technical field [0001] The invention relates to chemical equipment, in particular to equipment for synthesizing furanone with environmentally friendly technology and little damage to the environment. Background technique [0002] Furanone natural products exist in strawberry, oats, cheese, boiled beef, beer, cocoa, coffee, tea, mango, lychee, malt, gooseberry, grape, heated beef, pineapple, etc., in 1965, in the ether extraction of pineapple juice For the first time, furanone was isolated from the solution, and its molecular structure was determined. Furanone has strong caramel flavor, low fragrance threshold, and obvious fragrance effect, and is widely used as an additive in food, tobacco, beverages, etc. [0003] The synthesis methods of furanone are mainly divided into the following types from different raw materials: (1) using sugars as raw materials; (2) using furan derivatives as raw materials; (3) using unsaturated diol derivatives as raw materials; (4) Carboxylic a...
