n.二酸

Diacid has been got using diethylene glycol as decomposition agent of adduct. 采用二甘醇作為加合物的分解劑,得到了二元酸。

Diamine is synthesized of diacid by aminating and hydryzing process etc.. It is an importantly chemical intermediate. 二胺由二元酸通過氨化、氫化等工藝合成,是一種重要的化工中間體。

Acetanilide and hexane diacid,potassium hydrogen phthalate could improve PVC crystallinity. 乙酰苯胺、己二酸和鄰苯二甲酸氫鉀可以使PVC結(jié)晶度增大。

Acetanilide and hexane diacid, potassium hydrogen phthalate could improve PVC crystallinity. 乙酰苯胺、己二酸和鄰苯二甲酸氫鉀可以使PVC結(jié)晶度增大。

The approach involves chlorization,hydrolyzing the ester,preparing disodium,carboxylate to diacid,sulfonation. 研究了中間產(chǎn)物重結(jié)晶條件和結(jié)構(gòu)參數(shù)。

So far, we have synthesized pentadecane diacid , which is a very important intermediate product during preparing muscone. 到目前，我們已經(jīng)合成了制備麝香酮中重要的一步中間產(chǎn)物十五碳二羧酸。
