应用
Diethyl malonate is used in organic synthesis for the preparation of alpha-aryl malonates, mono-substituted and di-substituted acetic acid, barbiturates and artificial flavorings. It is also involved in the synthesis of pharmaceuticals like chloroquine, butazolidin and barbital. It acts as intermediate in the synthesis of vitamin B1, vitamin B6, non-steroidal anti-inflammatory agents agrochemicals and perfumes. In Knoevenagel condensation reaction, it reacts with benzaldehyde to get diethyl benzylidenemalonate. 备注

产品说明 一般描述 丙二酸二乙酯是丙二酸的二乙酯形式。使用氯化镁和三乙胺对丙二酸二乙酯进行酰化已有报道。通过K2CO3-催化的，丙二酸二乙酯与各种取代形式的1,2-丙二烯酮的1,4加成反应，可得到多官能化的β,γ-不饱和烯酮。 应用 利用沸石催化剂(通过在Nax和CSNax沸石上接枝氨基得到)，使用丙二酸二乙酯对微反应器中的Knoevenagel缩合反应进行研究。它可以通过碱催化与苯甲醛进行Knoevenagel缩合，以合成二亚苄基丙二酸酯。它可用于合成α-芳基丙二酸酯。 包装 1, 2.5 kg in poly bottle
