This allyl type of resin is a highly transparent, colourless material . 这种烯丙基型的树脂是一种高度透明的、无色材料。
These peaks correspond to side-chain cleavage of the ethyl and propyl groups respectively . 这些峰分别相当于乙基和丙基的侧链开裂。
This sequence constitutes an efficient method for preparing arylcyclopropylacetylenes . 这种反应构成了制备芳基环丙基乙炔的有效方法。
Of these end groups those having an allylic chlorine might be expected to show the highest activity . 在这些端基中,带有烯丙基氯原子的端基活性最高。
We see the symmetry we have attributed to allylic particles on the basis of the resonance theory; the two ends of each of these molecules are equivalent . 我们看到了曾经根据共振论而归因于烯丙基型粒子的对称性,所有这些分子中每个分子的两端都是等性的。
