摘要： The invention relates to a method for the production of tetrahydrogeranylacetone (tetrahydropseudoionone) by means of aldolcondensation of citral with acetone and subsequent hydrogenation. The invention also relates to the utilization of the tetrahydrogeranylacetone thus obtained for the production of phytol, isophytol, tocopherol and/or tocopherol derivatives. The invention further relates to methods for the production of tocopherols and/or tocopherol derivatives.

摘要： The invention relates to a continuous process for producing pseudoionones of general formulas (I) and (I′) as well as isomers thereof, whereby: R1 represents CH3 or (a); R2 and R3 represent hydrogen, CH3 or C2H5, and; R4 and R5 represent hydrogen or CH3. These pseudoionones are produced by reacting an aldehyde of formula (II) with an excess of a ketone of general formula (III), whereby R1, R2 and R3 have the aforementioned meanings, in the presence of water and alkali hydroxide at an increased temperature and in a homogeneous solution. The inventive process is characterized in that: a) the intermixing of the homogeneous solution consisting of aldehyde, ketone and aqueous alkali lye occurs at a temperature ranging from 10 to 120 °C; b) the undissolved water and alkali hydroxide contained in the reaction mixture are subsequently separated out; c) while avoiding back mixing, the homogeneous reaction mixture is then guided through a reactor, which permits a residence time ranging from 2 to 300 minutes, at a temperature that is 10 to 120 °C higher than the boiling point of the lowest-boiling component and under a vapor pressure p ranging from 106 to 107 Pa; d) the reaction mixture is cooled by expansion; e) ketone is removed from the reaction mixture using vapor flowing in the opposite direction and; f) the raw product is dried and rid from excessive aldehyde and secondary components via a rectification column.
摘要翻译：本发明涉及用于制备通式（I）和（I'）的假阳离子及其异构体的连续方法，其中：R 1表示CH 3或（一个）; R 2和R 3代表氢，CH 3或C 2 H 5，，和; R 4和R 5代表氢或CH 3。这些假性离子是通过使式（II）的醛与过量的通式（III）的酮反应制得的，由此R 1，R 2和R 2 在水和碱性氢氧化物的存在下，在升高的温度和均匀的溶液中，具有上述含义。本发明的方法的特征在于：a）由醛，酮和碱性碱液组成的均匀溶液的混合在10至120℃的温度下进行; b）随后将反应混合物中所含的未溶解的水和氢氧化碱分离出来; c）同时避免反混合，然后将均匀的反应混合物引导通过反应器，其允许在比最低浓度的沸点高10至120℃的温度下2至300分钟的停留时间，沸腾成分，并且在10 -6至10 7 Pa范围内的蒸汽压力p; d）通过膨胀冷却反应混合物; e）使用沿相反方向流动的蒸汽从反应混合物中除去酮; f）将原料干燥并通过精馏塔除去过量的醛和次要组分。
