Potassium methoxysalicylate - Reference Information

synthesis (1) will 2,4? Dihydroxybenzoic acid is slowly added into sodium hydroxide alkaline aqueous solution, and the temperature is controlled below 30 ℃, when 2,4? After all dihydroxybenzoic acid is added and dissolved, the temperature is lowered to 20 ℃, dimethyl sulfate is slowly added dropwise, the temperature is controlled below 40 ℃, after the dropwise is completed, the temperature is kept at 30~40 ℃ for 6 hours, after the reaction is over, the temperature is raised to 60 ℃, stirred for 30 minutes, the unreacted dimethyl sulfate is completely decomposed, then the temperature is lowered to normal temperature, the PH is adjusted to 1 with 10% hydrochloric acid, and a large amount of white solid substances are precipitated, centrifuge, rinse with deionized water, dry, get 4? Methoxysalicylic acid crude;
(2) 4? The crude methoxysalicylic acid is added to deionized water, heated to 80 ℃, stirred for 0.5 hours, filtered while hot, dried to obtain 4? Pure methoxysalicylic acid;
(3) in the deionized aqueous solution of potassium carbonate, raise the temperature to 50 ℃, slowly add 4? Methoxysalicylic acid, adjust PH = 7, stop adding 4? Methoxysalicylic acid, stirring for 30 minutes, starting to recover solvent, cooling crystallization, suction filtration, 4? Crude potassium methoxysalicylate;
(4) will 4? The crude potassium methoxysalicylate is dissolved in 50% ethanol solution, the activated carbon is decolorized for 40 minutes, suction filtration, cooling crystallization, vacuum drying, and 4? Pure methoxy potassium salicylate.
effect potassium 4-methoxysalicylate (potassium 4-methoxysalicylate) has a structure similar to salicylic acid. it is a new type of medicinal whitening ingredient, which is used in cosmetics and plays a whitening role. it is an effective ingredient of cosmetics. Potassium 4-methoxysalicylate can coordinate cutin metabolism, correct abnormal epidermal hyperplasia, promote the discharge of melanin, achieve skin smoothness and whitening; it can also block the source of melanin production and improve self-healing. It can be used in conjunction with various types of whitening products to improve the whitening effect and has good development prospects.
