| 摘要 |
THE INVENTION RELATES TO A CONTINUOUS METHOD FOR PRODUCING ESTERS, IN WHICH AT LEAST ONE POLYOL ESTER OF FORMULA (I) (R¹-COO)mR² (I), WHERE R¹ REPRESENTS HYDROGEN OR AN OPTIONALLY SUBSTITUTED HYDROCARBON GROUP CONTAINING 1 TO 50 CARBON ATOMS, R² REPRESENTS AN OPTIONALLY SUBSTITUTED HYDROCARBON GROUP CONTAINING 2 TO 10 CARBON ATOMS, AND m REPRESENTS A NUMBER FROM 2 TO 10 AND IS SMALLER THAN OR EQUAL TO THE NUMBER OF CARBON ATOMS IN R², IS REACTED WITH AT LEAST ONE MONOHYDRIC ALCOHOL OF FORMULA (II) R³-OH (II), WHERE R³ REPRESENTS AN OPTIONALLY SUBSTITUTED HYDROCARBON GROUP CONTAINING 1 TO 30 C ATOMS, USING MICROWAVE RADIATION IN A REACTION TUBE, THE LONGITUDINAL AXIS OF WHICH EXTENDS IN THE DIRECTION OF PROPAGATION OF THE MICROWAVES OF A SINGLE-MODE MICROWAVE APPLICATOR, SO AS TO OBTAIN AT LEAST ONE ESTER OF FORMULA (III) R¹-COO-R³ (III), WHERE R¹ AND R³ HAVE THE MEANINGS INDICATED ABOVE. |
