abietic

基本解释

It is not necessary to use natural pure abietic acid and dehydroabietic acid and they are not easily obtained as standard substances.
该法不仅可以克服松香中各异物体及同系物的干扰,而且不必用极难制备和保存的天然纯枞酸和脱氢枞酸作标样。
The results show that these oleoresins have common characteristics of that of subgen.Pinus, but all their amount of abietic acid are more than 20 %.
发现它们基本上具有油松亚属松树松脂的共同特征,唯枞酸含量较高,均超过20%25;
The results of the analysis show the main product is a dehy- drogenated abietic acid, whose quality is up to the requirement of the potassium soap of rosin.
分析结果表明，反应产物主要为脱氢枞酸，其质量符合作为歧化松香钾皂的要求。
From rosin purified abietic acid was prepared by using abietic acid as stared material acylamino surfactant was synthesized by maleric anhydride and diethanolamine.
用松香纯化得到的松香酸(枞酸)与马来酸酐反应得马来海松酸;再与二乙醇胺反应制得松香马来酰胺基乙醇表面活情剂.
Conjugated unsaturation of abietic resin acids can be removed through catalytic hydrogenation to overcome the shortcomings of oxidation and color degradation in rosin.
将松香催化加氢可去除枞酸型树脂酸的共轭不饱和性,克服其易于氧化变色的缺点。综述了40多年来国内外对松香催化加氢反应的研究进展。
