权利人:RESEARCH FOUNDATION FOR THE STATE UNIV OF NEW YORK; UNIV NEW YORK STATE RES FOUND
摘要:The present disclosure relates to using green solvents to synthesize an array of imines, imine-related and imine-derived compounds in an efficient and eco-friendly matter, satisfying green chemistry requirements. Reaction embodiments are performed using solvents, such as ethyl lactate and dimethyl isosorbide, which are both individually characterized as green. In embodiments, solvents include lactic whey and/or water as co-solvents. In these green solvents, the synthesis process discussed herein can produce up to quantitative yields of product at room temperature in a short duration. Embodiments include a method of forming an imine, imine-related or imine-derived compound product. In embodiments, the methods include mixing an aldehyde reactant with a nucleophilic/nitrogen-containing reactant in a green solvent at a temperature between negative twenty degrees Celsius (−20° C.) and positive fifty degrees Celsius (50° C.); stirring the mixture; and forming an imine, imine-related or imine-derived compound product.

摘要:Hydroxybenzaldoxime O-ethers of the formula ##STR1## in which R 1 represents alkyl, n are obtained by a process in which a tert.-butoxy-benzaldoxime of the formula ##STR2## is reacted with alkylating agents of the formula n n R.sup.1 --X n n in which n R 1 has the abovementioned meaning and n X represents halogen or OSO 2 OR 1 , n wherein n R 1 again has the abovementioned meaning, n in the presence of a strong base and phase transfer catalyst and in the presence of a diluent at temperatures between 0° C. and 50° C., and the products are then treated with anhydrous acid at temperatures between 0° C. and 50° C., n Hydroxybenzaldoxime O-ethers can be used as intermediate products for the synthesis of compounds with a fungicidal, insecticidal and antimycotic activity. The tert.-butoxy-benzalodoxime starting material is a new compound.

发明人：DIMMIT JEFFREY HOWARD; KEARNS MARK ALAN; CHAMBLESS WILLIAM H
权利人:HENKEL KGAA
摘要:A method for the preparation of 2-hydroxyarylaldehydes from an aryloxy magnesium compound and formaldehyde, which comprises reacting at a temperature from 40-120° C., an aryloxy magnesium compound having an aryloxy anion and a non-aryloxy anion and in which (a) the non-aryloxy anion is more basic than the aryloxy anion such that when the aryloxy magnesium compound is brought into contact with an acidic species, the acid reacts more preferentially with the non-aryloxy anion to form an aryloxy magnesium salt and (b) the aryloxy anion has at least one free position ortho to the hydroxyl group in the aryloxy anion, with formaldehyde or a compound capable of giving rise to formaldehyde under the reaction conditions in the presence of a polar co-solvent capable of providing the non-aryloxy anion in the aryloxy magnesium compound characterized in that the non-aryloxy anion is selected from the group consisting of an oxide, a hydroxide, a carboxylate, a sulphate and a nitrate.

权利人:UNIV SOUTHERN MISSISSIPPI
摘要:Novel latex or emulsion compositions containing internally plasticizing and crosslinkable monomers derived from traditional semi-drying or non-drying oils are disclosed and claimed. The monomers are ethylenically unsaturated derivatives of long-chain olefinic compounds. Preferred embodiments include latex formed from acrylate or methacrylate esters of fatty alcohols. A process for the synthesis of the latex composition is also disclosed, which involves (a) polymerization of the ethylenically unsaturated derivatives of a long-chain olefinic compound in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from -5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These compositions are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.
