ricinoleic acid

By the benson rule of group additivity, standard formation enthalpy \%Δ\%\-f\%H\%\+Φ\-m(298,g) and standard entropy \%S\%\+Φ\-m(298,g) of ricinoleic acid and its reaction products were estimated, and by the Rihani rule of group additivity, the relation between heat capacity for an ideal gas \%C\%\+Φ\-\{p,m\}(\%T\%) of each above substance and the temperature was estimated.

　用Benson基团加和法估算了蓖麻醇酸及其各反应产物的标准生成焓ΔfHΦm(298,g)、标准熵SΦm(298,g),用Rihani基团加和法估算了这些物质的理想气体热容CΦp,m(T)与温度的关系,分别导出了蓖麻醇酸各反应的标准焓变ΔrHΦm(T)、标准熵变ΔrSΦm(T)、标准吉布斯自由能变化ΔrGΦm(T)、标准平衡常数KΦp(T)与温度之间的关系。

Chermical base of this odour absorber is zinc ricinoleate.

这种吸味剂的化学成分是蓖麻醇酸锌 ,它没有气味 ,对微生物也没有抑制作用 ,故而与香精、杀菌剂等常用吸味剂作用不同。
