Resistant to sea water , mineral oils , chain hydrocarbon , corrosion and impact 漆膜可耐海水、礦物油、鏈烴、腐蝕和碰撞。
Study on extraction and stability of pigment in the leaves of forsythia viridissima flower 分子連接性指數用于飽和鏈烴類化合物相關性的研究
Its molecular structure shows that it acts long carbochain as hydrophobic group and serves carboxyl and hydroxyl group as hydrophilic grouping 其分子結構特征為:以長碳鏈烴基為憎水基, ? coom為親水基團。
A . enzymes transform complex , recalcitrant aromatic and aliphatic hydrocarbons that are not easily biodegradable to simple fatty acids , thereby accelerating biological cleanup 答:酶能轉化復雜的,難降解的芳烴和直鏈烴類化合物,并不是輕易地將它們生物降解為為簡單的脂肪酸,而是加速生物清除的過程。
Gas chromatography - mass spectrometry ( gc - ms ) analyses showed that both potassium permanganate and chlorine could oxidate the organic matters with unsaturated functional groups into those with carboxyl , hydroxyl and aldehyde . and it was further revealed that after preoxidation by potassium permanganate , the sorts of organic matters were reduced remarkably , however , chlorination leaded to increase of the sorts of orgnic matters and brought some chloro - organics such as chlorobenzene , chlorophenol , and trichloro - ethane 通過色譜-質譜聯用( gc - ms )評價分析了高錳酸鉀和氯對有機物結構的改變,高錳酸鉀和氯均將原水中的一些不飽和性有機物氧化分解為一些含氧基團的有機物,如羧酸類、醇類和醛等有機物,但預氯化會在水中出現一些鹵代物,鹵代產物不僅出現在苯環上,而且出現在鏈烴上。
