Synthesis method

1. Phenol reacts with sodium hydroxide to generate sodium phenolate. After distillation and dehydration, carbon dioxide is passed through the carboxylation reaction to obtain salicylic acid sodium salt, which is then acidified with sulfuric acid to obtain the crude product. The crude product is refined by sublimation to obtain the finished product. Raw material consumption quota: phenol (98%) 704kg/t, caustic soda (95%) 417kg/t, sulfuric acid (95%) 500kg/t, carbon dioxide (99%) 467kg/t. This method is divided into normal pressure method and medium pressure method. (1) Normal pressure method: Prepare sodium phenolate with 50% sodium hydroxide solution so that the free base is within 1%. After dehydration under reduced pressure, add phenol as a solvent for azeotropic dehydration. Then sodium phenolate is carboxylated by passing dry carbon dioxide into the solvent phenol, and then acidified with sulfuric acid to obtain the finished product.

Add phenol and 50% sodium hydroxide into the reactor in a ratio of 1:1.02 (mol). The reaction is dehydrated, and the free base is controlled to ≤1%. After dehydration under reduced pressure, phenol is added as the solvent for azeotropic dehydration. Then, sodium phenolate is introduced into the phenol with dry carbon dioxide gas, and after the carboxylation reaction is performed for 3 hours, carbon dioxide is introduced for the second time for 2 hours, and then the phenol is recovered under reduced pressure, that is, the carboxylation is completed. Then add water to the above sodium salicylate solution to dissolve it into a 50% solution, add 7%-8% sulfuric acid under stirring to acidify to pH 1-2, then cool, filter, and vacuum dry to obtain salicylic acid. The crude product is then sublimated under reduced pressure to obtain the finished product salicylic acid with a content of 99%, with a yield of 50%-70%. (2) Medium pressure method Still using phenol as raw material, sodium phenolate is first made, carboxylated with carbon dioxide under medium pressure to generate phenol carbonate, and then pressurized for molecular rearrangement to generate sodium salicylate, which is then acidified Post-processing produces salicylic acid. Neutralize the phenol with 50% liquid caustic soda, dry under vacuum, and then cool the kettle temperature to 100℃ , slowly passDry carbon dioxide is added, and when the pressure in the kettle reaches 0.7-0.8Mpa, the flow of carbon dioxide is stopped. At this time, sodium phenol carbonate is generated, and then intramolecular rearrangement isomerization occurs at 130-140°C to become sodium salicylcarboxylate. , and then acidified with sulfuric acid to obtain crude salicylic acid. The crude product is sublimated under reduced pressure to obtain high-quality salicylic acid, with a content of 99% and a yield of more than 98%. Consumption quota (kg/t): phenol (98%) 704, caustic soda (95%) 417, sulfuric acid (95%) 500, carbon dioxide (99%) 467. (3) Preparation method: Phenol reacts with sodium hydroxide to form phenol sodium salt, and then synthesizes sodium o-hydroxybenzoate with carbon dioxide, and then acidifies to produce salicylic acid:The crude product is dissolved in water and decolorized by activated carbon , and then recrystallized and purified. (4) React the same amount of phenol and 50% sodium hydroxide at 105~130℃ to generate phenolSodium, control free base within 1%. After the reaction is completed, dehydrate under reduced pressure, and then use phenol as the solvent to azeotropically dehydrate. After cooling to 100°C, dry carbon dioxide was introduced to carry out carboxylation reaction for 3 hours, and the temperature increased from 128°C to 200°C. After the temperature drops, the solvent phenol is recovered. After 2 to 3 hours, carbon dioxide is introduced for carboxylation for 2 hours, and phenol is recovered under reduced pressure. (Another method of carboxylation is to pass carbon dioxide at 140 to 180°C, and control the reaction pressure to 0.7 to 0.8 MPa for carboxylation reaction for 12 hours.) After the carboxylation reaction is completed, add water to dissolve sodium salicylate and adjust it to 50% solution, add 7% to 8% sulfuric acid solution while stirring to bring the pH value to 1 to 2, cool, filter, spin dry, wash with water several times, spin dry, then heat and dissolve with distilled water, add a little
Amount activated carbon, boil, filter while hot, cool the filtrate and dissolve in distilled water again, filter and spin dry several times to obtain pure salicylic acid. The crude salicylic acid obtained can also be refined by sublimation under reduced pressure. The process reaction formula is:

Synthesis method

1. Mannitol can be extracted from kelp or seaweed, but electrolytic reduction or catalytic reduction with glucose or sucrose solution is more commonly used. Each is briefly introduced below.
(1) Extraction method from kelp: Add an appropriate amount of water to dried kelp and soak it at room temperature to swell, then stir continuously to dissolve the mannitol into the water. Use caustic soda to adjust the pH value of the washing water to above 12 and allow it to precipitate for more than 16H. Then use 1:1 sulfuric acid to adjust the pH value to neutral, then evaporate and concentrate until the relative density is 1.30~1.32 and then cool it. The supernatant liquid is then evaporated and concentrated until the relative density is 1.42~1.45. Thermal centrifugation removes salt and the concentrated solution is cooled. Crystallize and centrifuge to obtain crude mannitol. Recrystallize the crude product with boiling water, decolorize with activated carbon, elute chloride ions with alcohol, and dry to obtain pure mannitol.
(2) Electrolytic reduction method: Use glucose or sucrose as raw material to prepare a solution of appropriate concentration, adjust the pH value to 7.0 with sodium sulfate, and then add it to an electrolytic cell for electrolysis. The electrolyte is decolorized by activated carbon, vacuum concentrated, ethanol desalted, cooled and crystallized, and centrifuged to obtain crude mannitol. The crude mannitol is then recrystallized to obtain the fine product.
(3) Catalytic reduction method The catalytic reduction method is to process sucrose solution through hydrolysis, neutralization, catalytic hydrogenation and other operations to obtain crude sorbitol and mannitol solutions, which are then filtered, activated carbon decolorized, ion exchanged and concentrated. , crystallization, separation and other operations to obtain high-quality mannitol.

2.Aspergillus oryzae fermentation method

3.Glucose produced by hydrolysis of sucrose by reducing method It is then reduced with fructose to form a mixture of sorbitol and mannitol, which is then decolorized, separated and purified to obtain mannitol.
