巴康(Bacon)在马尼拉首次用挥发性溶剂以依兰花做试验,以石油醚作为溶剂获得0.7—1.0％的抽提物,它具有如下性质: 比重 30°/4° 0.940 折光指数 30° 1.4920 酯值 135 乙酰化后酯值 208 1911年巴黎的加拿(Charles Garnier)在留尼汪岛(R’eunion Island)开设一个提取工厂并开始生产依兰净油。由于这些净油具有鲜花的香气,所以很快引起巴黎香料工业的注意。到了1920年加拿的工厂迁移到留尼汪岛的庇敦(Piton),即圣保罗的附近,于是其他的制造商也参加了行业并在马
For the first time, Bacon used Manila with a volatile solvent to test ylang-ylang flowers. Using petroleum ether as a solvent, 0.7 to 1.0% of the extract was obtained. It has the following properties: Specific gravity 30°/4° 0.940 Refractive index 30° 1.4920 Ester value 135 Esterification after acetylation 208 In 1911, Charles Garnier of Paris opened an extraction plant on R’eunion Island and began production of ylang nectar. As these clean oils have the aroma of flowers, they soon caught the attention of the Parisian flavour industry. By 1920, the factory in Cana was relocated to Piton in Reunion, near São Paulo, so other manufacturers also participated in the industry and
