Problems solved by technology

[0006] This method for producing Potassium Sorbate is more loaded down with trivial details in technology, and synthetic reaction is to be medium with water, will make through processes such as concentration, cooling, filtration, drying, and its shortcoming is: 1, produce waste water, waste residue in the production; . If an organic solvent is used as the reaction medium, waste gas will be generated, and there may even be safety problems; 3. High production cost, long production cycle, large investment in equipment, and waste of energy

Embodiment 1

[0031] Example 1: Put 10kg sorbic acid and 0.5kgKOH into a vertical ball mill, adjust the rotating speed to 180 rpm, use water cooling to control the temperature between 25°C and 60°C, and then add 3.0kgKOH after 70 minutes 2 CO 3 , continue to grind for 100 minutes, during this period, if the temperature rises, you can stop grinding, add 10g CaO, and add 2.55kg K at the same time 2 CO 3 , Grinding ends in 120 minutes. Dissolution test and purity inspection are passed, dried at below 60°C, and packaged as a finished product.

Embodiment 2

[0032] Embodiment 2: get 5kg sorbic acid, add 0.28kgKOH and 1.38kgK 2 Put CO3 into a vertical ball mill reactor, adjust the speed to 220 rpm, use water cooling to keep the temperature below 80°C, grind for 50 minutes, and then add 0.69kg K 2 CO3, continue to grind for 70 minutes, add 6g of modified starch, add 0.54kg of KOH, 10g of microcrystalline cellulose at the same time, and finish grinding for 120 minutes. Dissolution test and purity inspection are passed, dried at below 60°C, and packaged as a finished product.

Embodiment 3

[0033] Embodiment 3: Put 20 kg of sorbic acid into a horizontal ball mill, add 1.48 kg of crystalline potassium carbonate, keep the pressure in the reaction system less than 0.08Mpa, and keep the temperature at 20°C to 50°C for grinding for 120 minutes, then add 8.6kg of K 2 CO3, continue to grind for 760 minutes, add 2.0kgKOH and 100g of diatomaceous earth and grind for another 120 minutes to complete the reaction, dry at 60°C, and pack.

Abstract

The invention relates to a method for synthesizing potassium sorbate, which comprises mixing and grinding sorbic acid, potassium hydroxide and / or potassium carbonate in a solid state for chemical reaction. The temperature is controlled at -2°C-80°C, and the pressure is controlled at 0.005Mpa-0.15Mpa. When solid sorbic acid and solid potassium carbonate, potassium hydroxide, and crystalline potassium carbonate are used as raw materials for solid-solid reaction to synthesize potassium sorbate, catalysts, retarders, and anticaking agents can be used to ensure the smooth progress of the reaction. The method has the advantages of: (1) the reaction is carried out at normal temperature, (2) the production process is simple, (3) the investment in equipment is small, (4) the factory building is small, (5) the power energy is saved, (6) no waste gas is produced, waste water, waste residue.

Description

technical field [0001] The invention relates to a method for synthesizing potassium sorbate, in particular to a method for synthesizing potassium sorbate by chemical reaction by mixing and grinding solid reactants such as sorbic acid and solid alkali. Background technique [0002] Potassium sorbate is an internationally recognized low-toxicity and high-efficiency food preservative. It can inhibit mold, yeast and aerobic bacteria. It can be used for the preservation of jam, fruit juice, candied fruit, wine, soy sauce, vinegar and other foods. Used in food processing industry. [0003] At present, the production process of potassium sorbate is a mature process commonly used at home and abroad, and can be roughly divided into the following two categories: [0004] Sorbic acid + potassium carbonate (potassium hydroxide) → neutralization reaction → concentration → cooling → crystallization → filtration → drying → packaging [0005] Sorbic acid + potassium carbonate (potassium h...
