adj.脂環(huán)族的

Blending polycarbonate with aliphatic or alicyclic polyester is a valuable method to improve t... 而脂肪族或脂環(huán)族聚酯共混改性聚碳酸酯是提高其綜合性能的一條好途徑。

In this paper, two unsaturated alicyclic nitrogen heterocyclic crownethers were synthesized by phase transfer reaction . 采用相轉(zhuǎn)移催化反應(yīng)合成了兩個(gè)不飽和脂環(huán)氮雜冠醚。

The electrical insulation properties of epoxy resins cured with alicyclic anhydrides of different chemical structures were similar. 不同化學(xué)結(jié)構(gòu)脂環(huán)酸酐固化后的環(huán)氧樹(shù)脂電氣絕緣性能相近。

Therefore, the content of paraffinic &alicyclic hydrocarbons and aromatic hydrocarbons in these heavy oils can be characterized by this method. 研究結(jié)果表明:前三種油的氫碳原子比、芳香度與重質(zhì)油的飽和烴加環(huán)烷烴、芳烴含量之間存在著良好的線性關(guān)系,可用線性方程來(lái)表示。

Over the past four decades,many dearomatization reactions have developed and applied for synthesis of alicyclic compounds containing six-membered carboncyclic moieties. 芳香族化合物穩(wěn)定、易得,通過(guò)芳香族化合物的脫芳構(gòu)化反應(yīng),制備官能化的脂肪六元碳環(huán)化合物,早已引起人們的廣泛興趣。
