Application of 33893-85-5, Adding some certain compound to certain chemical reactions, such as: 33893-85-5, name is 4-(Hydroxymethyl)cyclohexanol,molecular formula is C7H14O2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 33893-85-5.
Operation steps: The four-necked flask is equipped with a stirring paddle, a thermometer, a water separator, and a reflux condenser is connected to the upper part of the water separator. 150.2g of p-methylolcyclohexanol and 92g of acrylic acid were placed in a 500mL four-necked flask, and 4.2g of p-hydroxyanisole, 8.6g of p-toluenesulfonic acid, 1.95g of hypophosphorous acid, and 80g of toluene were added. After stirring, the vacuum pump was started at 30KPa When the temperature is raised to 86 C, the reflux flow rate of the solvent in the reflux condenser is stable, and a water layer appears in the water separator. The water output is recorded once every hour. When the water output is less than 0.1g / h, the reaction is completed and the reaction time is 16 ~ 18h.After the reaction, the temperature was lowered to 45 C., 80 g of toluene was added to the product after the reaction, and 50 g of water was added for washing. After stirring at 40 C. for 5 minutes, it was placed in a separating funnel and allowed to stand for water separation. At 40 C, 50g of 1N sodium bicarbonate and 1N sodium hydroxide aqueous solution were added to neutralize, and the mixture was left standing to separate water. This operation was repeated 3 times. After neutralization is completed, add 0.3g of p-hydroxyanisole, spin-dry the solvent,Obtained colorless transparent viscous monomer A3,
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 33893-85-5, 4-(Hydroxymethyl)cyclohexanol, other downstream synthetic routes, hurry up and to see.
