2,2-二羟甲基-1,3-丙二醇单缩醛的合成

SYNTHESIS OF MONOACETALS OF 2,2 BIS(HYDROXYMETHYL) 1,3 PROPANEDIOL

引言２，２－二羟甲基－１，３－丙二醇（以下称季戊四醇）单缩醛是有机合成的重要中间体。我们曾用季戊四醇单缩醛与氢化钠及１，３－丙磺内酯反应合成了一系列含有１，３－二氧六环的磺酸盐型可断裂表面活性剂［１］。目前，有关季戊四醇单缩醛的文献报道极少。Ｃｏｎｒ...

Monoacetals of 2,2 bis(hydroxymethyl) 1,3 propanediol were prepared by condensation of aldehydes with 2,2 bis(hydroxymethyl) 1,3 propanediol in dimethyl sulfoxide.The prducts were characterized by 1HNMR, IR and elemental analysis.
