| Production method | After sulfonating cyclohexylamine with chlorosulfonic acid or sulfamate to cyclohexylsulfamic acid, it is neutralized and refined with sodium hydroxide. Synthesis of Cyclohexylamine and Sulfur Trioxide This is the production method of Baldwin-Montrose Chemical Company in the United States. (CH3)3N SO3 →(CH3)3NSO3[C6H11NH2] →[NaOH] → C6H11NHSO3Na Dissolve trimethylamine and sulfur trioxide in tetrachloroethylene solvent respectively, and then mix and react to form a suspension of trimethylamine-sulfur trioxide complex. This suspension is then added to an aqueous solution of cyclohexylamine and sodium hydroxide, and reacted at 60~70°C to form sodium cyclohexanesulfonate. 40g of liquid SO3 can also be dissolved in 200 mLCH2C12, added dropwise to 150mL of solution dissolved with 56g of triethylamine at-I0 ℃, and reacted at a constant temperature for 15min to generate triethylamine sulfur trioxide complex. The equimolar cyclohexylamine was added dropwise at 20 ℃ for 1h. After the reaction was complete, NaOH solution of 250mL 10% was added and reacted at 60 ℃ for 1h. The product is obtained by concentration, cooling, crystallization, suction filtration and drying of the separated water layer, and the yield is about 95%. In addition, Japan's Nido Chemical Company adopts the process route of gas phase reaction of sulfur trioxide and cyclohexylamine. Cyclohexylamine and sulfamic acid (or salt) synthesis method Japan Jifu Pharmaceutical Co., Ltd. uses cyclohexylamine and sodium sulfamate as raw materials to produce cyclamate. The reaction is carried out in a light oil solvent at 180~200 ℃. After the reaction, it is crystallized and recrystallized to obtain the finished product, and the mother liquor is returned to the reactor for reuse. This method is easy to obtain raw materials, simple operation, easy recovery of solvent and high yield. Domestic research on the optimization of the process conditions reported that 25g of cyclohexylamine was added dropwise to a mixture of 10g of sulfamic acid and 35g of light oil, reacted at 165 ℃ for 3h, then cooled to below 130 ℃, 41g of 10% sodium bicarbonate solution was added to dissolve the product, then distilled to recover light oil and cyclohexylamine, and finally the crude product was recrystallized with 97.5% yield. C6H11NH2 + NH2SO3Na → C6H11NHSO3Na + NH3 ↑ Japan Toyo Chemical Co., Ltd. uses cyclohexylamine and sulfamic acid as raw materials to produce cyclamate at 160~179 ℃ and o-dichlorobenzene. The second reaction temperature is controlled below 130 ℃. The unreacted cyclohexylamine and o-dichlorobenzene are steamed out with steam and reused. The reactants are crystallized and recrystallized to obtain the finished product. The raw materials of this method are cheap and easy to obtain, the solvent is easy to recover, the reaction time is short, and the yield is high. 2CaH11NH2 + NH2SO3H → C6H11NHSO3NH3C6H11[NaOH] → Synthesis of C6H11NHSO3Na Cyclohexylamine and Chlorosulfonic Acid This is the production method of a Japanese company. 2C6H11NH2 + ClSO3H[<5 ℃ = → C6H11NHSO3NH3C6H11[NaOH] → C6H11NHSO3Na reaction After separation, concentration and extraction, 95% finished products are obtained. The method has cheap raw materials and fast reaction, but has more side reactions and serious equipment corrosion. Using cyclohexylamine as raw material, sulfonated with chlorosulfonic acid or sulfamate to cyclohexylsulfamic acid and then reacted with sodium hydroxide. |
