Application of 116-02-9 ,Some common heterocyclic compound, 116-02-9, molecular formula is C9H18O, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
1, equipped with a stirrer, condensate return pipe, thermometer, N.2The four-necked flask was purged with nitrogen and the addition of acrylic acid and 3,3,5-trimethylcyclohexanol, the molar ratio of acrylic acid to 3,3,5-trimethylcyclohexanol was 1: 1.2, , Stirring speed of 300 r / min, heating up; 2, continue to heat up to 118 , stable condensate reflux, adding catalyst, incubation reaction 4h; and then remove the condenser, install the water separator, at 125 reaction 3h, stop And then distilled at a temperature of 80 C and a pressure of -0.099 MPa to obtain a pale yellow transparent product with an acrylic acid conversion of 94.6% and a yield of 85.14%.The catalyst is p-toluenesulfonic acid in an amount of 1.0% by weight based on the total weight of the total reactants.
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. 116-02-9, 3,3,5-Trimethylcyclohexanol, other downstream synthetic routes, hurry up and to see.
