• [EN] PREPARATION PROCESS OF ORTHO ALKOXY BISPHENOL MONOMERS<br/>[FR] PROCÉDÉ DE PRÉPARATION DE MONOMÈRES D'ORTHOALCOXY BISPHÉNOL

  A process for making ortho alkoxy bisphenol monomers includes contacting an (alk-1-enyl)alkoxyphenol (type 1) with an alkoxyphenol (type 2) in the presence of an acidic catalyst. Both type of renewable phenols (type 1 and 2) can be generated from lignocellulosic biomass. The use of such alkoxy phenols as a precursor to bisphenol monomers has the potential to reduce the cost and environmental impact of structural materials, while meeting or exceeding the performance of current petroleum-derived polymers, such as thermoplastics and thermoset resins.

  制备邻烷氧基双酚单体的过程包括将（烯基）烷氧基酚（类型1）与烷氧基酚（类型2）在酸性催化剂存在下接触。这两种可再生酚（类型1和2）均可从木质纤维素生物质中生成。将这种烷氧基酚用作双酚单体的前体有潜力降低结构材料的成本和环境影响，同时满足或超越当前石油衍生聚合物（如热塑性塑料和热固性树脂）的性能。

  The invention entitled “A Microwave Induced One Pot Process for The Preparation of Arylethenes” provides a method for the preparation of commercially important 2- or 4-hydroxy substituted arylethenes like styrenes or stilbenes in one pot utilizing cheaper substrates in the form of 2- or 4-hydroxy substituted cinnamic acids and their derivatives as well as reagents in the form of base such as sodium hydroxide, potassium hydroxide, lithium hydroxide, sodium bicarbonate, sodium carbonate, potassium bicarbonate, potassium carbonate, ammonium acetate, imidazole, methylimidazole and the combination thereof, with or without solvent such as dimethylformamide, dimethylsulfoxide, ethylene glycol, diethylene glycol, acetonitrile, acetone, methyl imidazoles, ionic liquid, water and the like. The reaction time vary from 1 min-12 hrs and yield of the products from 49-76% depending upon the base, acid, substrate source of heating monomode or multimode microwave or conventional. It is important to mention that the presence of 2- or 4-hydroxy substitution at phenyl ring of cinnamic acids and their derivatives is essential requirements towards formation of corresponding arylethenes in one step.

  这项名为“一锅法微波诱导制备芳基乙烯”的发明提供了一种在一个反应器中利用更便宜的底物（2-或4-羟基取代肉桂酸及其衍生物）和碱性试剂（如氢氧化钠，氢氧化钾，氢氧化锂，碳酸氢钠，碳酸钠，碳酸氢钾，碳酸钾，乙酸铵，咪唑，甲基咪唑和它们的组合物）制备商业上重要的2-或4-羟基取代的芳基乙烯（如苯乙烯或苯并乙烯）的方法。反应时间为1分钟至12小时，产率为49-76％，取决于碱性试剂、酸性试剂、底物、加热方式（单模或多模微波或传统方式）等因素。值得一提的是，肉桂酸及其衍生物苯环上的2-或4-羟基取代是制备相应芳基乙烯的必要条件，可以在一个步骤中完成。反应可以在溶剂（如二甲基甲酰胺、二甲基亚砜、乙二醇、二乙二醇、乙腈、丙酮、甲基咪唑、离子液体、水等）存在或不存在的情况下进行。

  A coffee extract or concentrate and a soluble coffee which are similar to roast and ground coffee solubles in composition of moderately volatile flavor components are disclosed. The soluble coffee composition also contains less of the off-flavor components normally found in high quantities in conventional instant coffees. The coffees are characterized by high pyrazines derivative content and low content of furfural. This soluble coffee composition can be aromatized for use as a premium soluble coffee product. Alternatively, it is compatible for mixing with conventional roast and ground coffee in single- and multiple- serving brewing articles, such as coffee bags.

  本发明公开了一种咖啡萃取物或浓缩物以及一种可溶咖啡，它们与烘焙咖啡和研磨咖啡溶液中的中度挥发性风味成分相似。 这种可溶咖啡成分还含有较少的通常在传统速溶咖啡中大量存在的异味成分。 这种咖啡的特点是吡嗪衍生物含量高，糠醛含量低。 这种可溶咖啡成分可以进行芳香化处理，用作优质可溶咖啡产品。 另外，它还可以与传统的烘焙咖啡和研磨咖啡混合，制成单份或多份冲泡物品，如咖啡袋。
