The preparation of 1-ethylcyclohexyl acrylate: take the also logical drying nitrogen protection in 500ml there-necked flask of 6.2g (0.26mol) magnesium chips.Take 32.0g (0.296mol) monobromethane, 46.0g tetrahydrofuran (THF) to mix with 60.0g toluene and be placed in constant pressure funnel, interior temperature is 13 DEG C.In magnesium chips, add the mixed solution of 5mL tetrahydrofuran (THF), toluene and monobromethane, after reaction causes, a large amount of heat release, interior temperature rises to 35 DEG C, and solution becomes grey and has white cigarette to emerge.When interior temperature drops to 15 DEG C, start the mixed solution of lasting dropping monobromethane, tetrahydrofuran (THF) and toluene and open stirring.In controlling, warm <35 DEG C, 1h drip complete, stir 1 hour under being then transferred to room temperature (20-30 DEG C), obtained Grignard reagent.
