摘要： The present application belongs to the technical field of epoxy resins, and more particularly relates to a preparation method and application of a low-chlorine epoxy resin, which aim to solve the problem of high chlorine impurity content of an epoxy resin. The preparation method includes the following steps: performing an aldol condensation reaction of a bisphenol A epoxy resin containing chlorine impurities and the polyfluoroalkyl aldehyde under a first preset reaction condition to obtain a reaction product; adding a perfluoroalkane solution to the reaction product for extraction, standing and then separating to obtain an extract phase and a raffinate phase, the extract phase including a fluorine-containing chlorinated product, the raffinate phase including a low-chlorine bisphenol A epoxy resin; and separating the extract phase from the raffinate phase, so as to achieve the purpose of separating a chlorine-containing bisphenol A epoxy resin from a chlorine-free bisphenol A epoxy resin, thereby obtaining the low-chlorine bisphenol A epoxy resin, wherein the chlorine content of the low-chlorine bisphenol A epoxy resin is lower than that of the bisphenol A epoxy resin before reaction.

摘要： The present invention describes compounds produced from an orotic acid molecule and an ammo acid molecule The compounds, which include an amide linkage, are represented by the general Formula (I), wherein R is selected from the group consisting of (CH3)2CHCH2-, (CH3)2CH-, CH3CH2CH(CH3)-, H2NC(=NH)NH(CH2)3-, and C6H5CH2- Formula (I). The compounds are produced by one of two disclosed methods 1) reacting orotic acid or derivatives thereof with a thionyl halide, and then combining the acyl halide with an ammo acid in the presence of dichloromethane and a dimethylammopyπdme (DMAP) catalyst, or 2) protecting the carboxylic acid of an ammo acid with a benzyl group, and then combining the benzyl-protected ammo acid with a dicyclohexylcarbodiimide (DCC) activated orotic acid, followed by removal of the protecting group. The resulting ammo acid orotate amide compounds are aimed at providing enhanced stability in solution compared with the related esters.

摘要： A method to prepare new polymorphs of materials which have not been observed or to obtain a known polymorph under different conditions than those in which it is usually made by using a laser to cause nucleation and crystal growth to occur in a supersaturated solution in such a way as to obtain a crystal structure which would not normally appear without the use of the laser. For example, laser light can cause spontaneous nucleation of gamma-glycine crystals from a supersaturated aqueous solution.

摘要： Reversible switchable surfactants are provided. A surfactant is the salt of an amidine or guanidine having at least one R group that is a hydrophobic moiety selected from the group consisting of higher aliphatic moiety, higher siloxyl moiety, higher aliphatic/siloxyl moiety, aliphatic/aryl moiety, siloxyl/aryl moiety, and aliphatic/siloxyl/aryl moiety. The other R groups are smaller moieties such as H1 C1 to C4 aliphatic or the like. The surfactant is turned on by a gas that liberates hydrogen ions, such as, for example, carbon dioxide, which liberates hydrogen ions in the presence of water. The surfactant is turned off by exposure to a flushing gas and/or heating. When 'on' the surfactants are useful to stabilize emulsions, and when 'off' they are useful to separate immiscible liquids or a liquid and a solid. The surfactants find uses in polymerization and in the oil industry.

摘要： A process for the isolation of substantially pure ascorbyl-6-fatty acid ester from the products obtained by the sulphuric acid-catalyzed esterification of ascorbic acid with fatty acids comprises extracting with diethyl ketone such reaction products from the mixture remaining after the esterification reaction, hydrolysing the sulphate ester by-products in the diethyl ketone extract, removing the generated sulphuric acid from the product of this hydrolysis, isomerizing the ascorbyl-5-fatty acid ester by-product to the desired ascorbyl-6-fatty acid ester by acid catalysis in a non-polar aprotic organic solvent, and recovering the accumulated ascorbyl-6-fatty acid ester. As another aspect, the present invention provides a process for the manufacture of fatty acid esters of ascorbic acid, said process comprising the initial step of reacting ascorbic acid or an alkali metal or alkaline earth metal salt thereof with a fatty acid or with a lower alkyl ester or an alkali metal salt or alkaline earth metal thereof in concentrated sulphuric acid, and subsequent steps based on the above-described isolation process.
