摘要
芳樟醇是一种重要的香料产品,广泛用于合成香料、医药、调香及食品和饲料等工业领域,
    除用在一些重要香精的调配配方中外,还是合成维生素A、E和β—胡萝卜素的重要中间体,
    同时作为原料可以合成出乙酸芳樟酯等一系列更有价值的合成香料产品。
     蒎烷氢过氧化物、蒎烷醇均是合成芳樟醇的必备中间体,同时它们还可作为化学试剂单独
    参与反应而加以利用。本文以高顺式选择性蒎烷为原料,经液相空气氧化制得蒎烷氢过氧化物,
    再经催化还原得到高得率蒎烷醇。筛选出了理想的氧化、还原催化剂,考察了主要因素对氧化、
    还原反应的影响,优化出了最佳工艺条件。氧化最佳工艺条件为:反应温度95℃、反应时间
    9hs、空气流量40L/h、催化剂用量5‰,目的产物最大得率达到37.02%。还原反应最佳条件
    为:反应温度35℃、反应压力6MPa、反应时间5hs,目的产物最大得率达到90.06%。为后序
    高温裂解制芳樟醇和工业化推广奠定了较为坚实的基础。
Linalool is an important kind of synthetic perfumes. It is widely used in such fields as the synthetic perfume indusuy, the medicine industiy and the chemical industiy concerned with products for daily use. Linalool is often used as important component in some useful perfumery compounds, and important inteimediate in the process of the synthesis of VA and VE. We can also produce more useful synthetic perfumes from it.
    Both pinane hydroperoxide and pinanol are essential intermediates in the process
    of the synthesis of linalool, and they can be utilized in many other chemical reactions solely as chemical material. In this thesis, pinane hydroperoxide and pinanol are obtained from the initial material -?pinane with high cis-pinane content In the
    systhetic process, two unit reaction ?oxidation reaction with air in liquid phase and catalytic deoxidation reaction are emphatically concerned. Ideal catalysts are selected, main factors influencing reactions are experimented, and optimum conditions are obtained. The maximum yield of pinane hydroperoxide 3 7.02% is reached under the optimum oxidizing conditions ?temperature 95C, time 9hs, flow of air 4OIJhr and amount of catalyst 5%o. The maximum yield of pinanol 90.02% is reached under the
    optimum catalytic deoxidizing conditions ?temperature 35C, pressure 6IvIPa and time 5hs. All of these provide firm foundation for the synthesis of linalool and the utilization of this technology in industry field.
