| titleOfInvention | The preparation method of 3 tetrahydrofurfuryl carbinols |
| abstract | The preparation method of 3 tetrahydrofurfuryl carbinols of the invention is related to insecticide preparation field, and in particular to the preparation method of 3 tetrahydrofurfuryl carbinols, comprises the following steps：Take 13.6g caustic alcohols,0.5g sodium iodides are dissolved in 120mL absolute ethyl alcohols,32g diethyl malonates are added dropwise under ice-water bath,Temperature is controlled in less than 20 DEG C,Continue to stir 1h after being added dropwise,It is then slowly added to 30.3g bromoacetates,After raise temperature to 50~60 DEG C,Stir about 8h,Gas chromatographic detection bromoacetate exhausts,Stop heating response,Cooling system is to room temperature,Stirring is lower to add saturated ammonium chloride solution 10mL,Regulation system is to neutral or slightly biased acidity,Boil off etoh solvent,Residue adds 100mL water and 100mL ethyl acetate dissolution extractions,Liquid separation,Isolate organic phase,Organic phase sloughs solvent ethyl acetate,Oil pump is evaporated under reduced pressure,Collect first cut point,As product 1,1,2 ethane tricarboxylic acids triethyls,Purity；Present invention process is simple, ensures the security in actual production, the acquisition product for having higher yields. |
