The invention relates to a continuous method for producing aliphatic carbonic acid esters by reacting at least one aliphatic carboxylic acid of formula (I) R
1
—COOH (I), wherein R
1
represents hydrogen or an optionally substituted aliphatic hydrocarbon group with 1 to 50 carbon atoms, with at least one alcohol of formula (II) R
2
—(OH)
n
(II), wherein R
2
represents an optionally substituted hydrocarbon group with 1 to 100 C atoms and n is an integer from 1 to 10, in the presence of at least one transesterification catalyst in a reaction tube the longitudinal axis of which extends in the direction of propagation of the microwaves of a monomode microwave applicator, under microwave irradiation to form the ester.
该发明涉及一种连续生产脂肪族
碳酸酯的方法,通过在至少一种脂肪族
羧酸(
化学式(I)R1—COOH(I),其中R1代表氢或具有1至50个碳原子的可选择取代的脂肪烃基)与至少一种醇(
化学式(II)R2—(OH)n(II),其中R2代表可选择取代的具有1至100个碳原子的碳氢化合物基团,n为1至10的整数)在至少一种酯交换催化剂存在下,在反应管中进行反应,该反应管的纵轴沿着单模微波应用器的微波传播方向延伸,在微波辐照下形成酯。
