Organic oligomers of acylglycerol

A process for treating plants, including the application of at least one compound, termed carbonic ester of glycerol, including at least one carboxylic ester function formed by a carbonic acid-derived group and at least one glycerol-derived group, with the exception of cyclic glyceryl carbonate including five ring members.

Use of acylated carbonic esters of glycerol in agriculture

A method for synthesizing dimethyl carbonate from methanol and urea, in which a saline ureic medium is used that includes at least one inorganic salt selected from the group made up of zinc (Zn) (II) chloride, tin (Sn) chlorides and iron (Fe) (III) chloride, characterized in that: methanol, in the presence of a catalytic composition, is placed in contact with the saline ureic medium that is at least partially liquid at a temperature referred to as synthesis temperature, which is higher than 140&#xb0; C., such that reaction vapors are produced; the reaction vapors are condensed, and a condensate of the reaction vapors is collected, including dimethyl carbonate; the method is carried out at atmospheric pressure. A method for enriching and purifying dimethyl carbonate is also described.

A method of oxidative molecular cleavage of a fatty compound, includes:&#x2014;forming a liquid composition, referred to as a fatty composition, consisting of at least one aliphatic carboxylic acid, the fatty composition including the fatty compound; characterized in that it then involves:&#x2014;adding, to the fatty composition, a solution of at least one quaternary ammonium salt in water capable of forming an emulsion from the fatty compound and water, then;&#x2014;adding, to the emulsion, a liquid solution of at least one tungstophosphoric acid in a composition including hydrogen peroxide (HO), in such a way as to form, in situ in the emulsion, a quantity of a phase-transfer catalyst, formed from tungstophosphoric acid and at least one quaternary ammonium from the quaternary ammonium salt(s), and to allow the oxidative molecular cleavage of the fatty compound.

Method of oxidative molecular cleavage of a fatty compound

The invention relates to polyesters containing at least one partly acylated polyhydroxylated compound belonging the group consisting of glycerol polycarbonates, specific polyglycerols, [(a-hydroxymethyl) oxyethylene/(a-hydroxymethyl)ethylene carbonate] copolymers, [a -hydroxymethyl) oxyethylene/(a-hydroxymethyl)ethylene carbonate] copolymers, and [a -alkyl) oxyethylene/(a-hydroxyalkyl) oxyethylene] copolymers. The invention also relates to methods for acylating, at least partly, the polyhydroxylated compounds. The polyesters of this invention are applicable to the technical fields relating to engine and industrial lubricants, greases, hydraulic fluids, metal deformation and processing lubricants, stripping and mold dressing products, oil prospecting, mines, tunnel borers, cosmetics, detergency, inks, textile coatings and papers, to the field of food products, to the protection of wood as synthesis intermediates.

Glycerol polycarbonate polyesters and other polyhydroxylated polymers and copolymers, acetylation method and applications

A process for making carbohydrate partial esters having a degree of esterification of from 1 to 6 involving the steps of: (a) providing a catalytically active mixture containing: (i) an alkali metal carbonate; and (ii) a fatty acid lower alkyl ester; (b) providing an emulsifier mixture containing: (iii) a glycose component having from 5 to 12 carbon atoms; and (iv) a carbohydrate partial ester; and (c) combining the catalytically active mixture with the emulsifier mixture, with vigorous stirring, to form an emulsion/dispersion containing particles having a mean diameter of from 10 to 60 &mgr;m.

The invention concerns a method for preparing glycerol carbonate. This method consists of making urea and glycerol react at a temperature substantially between 90.degree. C. and 220.degree. C. in the presence of a catalyst bearing Lewis acid sites, in particular metallic or organometallic salts or supported metallic compounds. The invention enables glycerol carbonate to be obtained, by a catalytic carbamoylation/carbonation reaction, in a highly pure state under economic conditions.
