METHOD FOR PRODUCING IRON CARBONATE

The purpose of the present invention is to provide a method for producing an iron carbonate, whereby it becomes possible to prevent the generation of hydrogen during the production of the iron carbonate by the reaction of a carboxylic acid with metal iron. An embodiment of the present invention is a method for producing an iron carbonate by reacting metal iron with a carboxylic acid in a reaction solution, wherein a compound of trivalent iron is added to the reaction solution, the reaction solution contains a compound of trivalent iron at the time of the start of the reaction, the reaction solution contains a non-iron metal having a standard electrode potential of -2.5 to 0.1 inclusive or a metal compound containing the metal, or the reaction solution contains at least one metal selected from the group consisting of Ag, Bi and Pd or a metal compound containing the metal.

Hydroxy functional acrylate and methacrylate monomers prepared via lipase-catalyzed transacylation reactions

Candida antarctica lipase B (CAL-B, Novozyme 435) catalyzes the transacylation of methyl acrylate and methyl methacrylate with diols and triols in 2-methyl-2-butanol at 50 °C. Under the experimental conditions, up to 70 mol% of the acyl donor methyl acrylate was converted. Methyl methacrylate is the less efficient acyl donor (up to 60 mol%) due to the higher sterical hindrance in the enzymatic transacylation. Under the reaction conditions high yields of the mono-acylated products are obtained, which contain minor amounts of bis(meth)acrylates. In addition it was observed that Novozyme 435 catalyzes regioselectively the acylation of the primary hydroxyl groups. In comparison with the chemical catalyzed route no selectivity was observed for unsubstituted diols. For substituted diols more mono-acylated product was formed in the lipase-catalyzed reaction than in the chemical catalyzed reaction.

Separating material

The present invention provides a separating material producable by a) providing a solid substrate, having amino-functional groups coupled to the substrate surface, b) covalently coupling of the amino-functional groups with a thermally labile radical initiator, c) contacting the substrate surface with a solution of polymerizable monomers under conditions, where thermally initiated graft copolymerization of the monomers takes place, to form a structure of adjacent functional polymer chains on the surface of the substrate. The present invention further provides a method for the production of a separating material by a) providing a solid substrate, having amino-functional groups coupled to the substrate surface, b) covalently coupling of the amino-functional groups with a thermally labile radical initiator, c) contacting the substrate surface with a solution of polymerizable monomers under conditions, where thermally initiated graft copolymerization of the monomers takes place, to form a structure of adjacent functional polymer chains on the surface of the substrate.

A process of preparing the same is also disclosed, as well as a novel class of compounds.

Adhesive composition

An adhesive composition comprises 100 parts by weight of a polymerizable monomer comprising (a) 1.5 to 100 parts by weight of a compound represented by general formula I or II: STR1 where R1 and R1 ' each stand for hydrogen or a methyl group, R2 stands for a divalent organic residue having 4 to 40 carbon atoms, X1 and X2 each stand for --O--, --S-- or --NH--, a is 0 or 1, and R3 stands for a group of the formula STR2 having 6 to 40 carbon atoms, where R4 and R4 ' each stand for a hydrocarbon group having 1 to 29 carbon atoms, and optionally replaced by a halogen atom, or a hydroxyl, amino or carboxyl group, b is an integer of 0 to 3, and Z stands for --O--, --COO-- or --NH--, a plurality of R4 ' (when b is 2 or 3) being the same or different, at least one of R4 and R4 ' having at least three carbon atoms, and (b) 0 to 98.5 parts by weight of a vinyl monomer copolymerizable with the above compound; and 0.01 to 20 parts by weight of a curing agent. It shows a superior adhesive strength on any of hard tissues in a living body, such as teeth and bones, metals, organic polymers and ceramics. It maintains a high adhesive strength for a long time even if it is exposed to moisture, or immersed in water. It is particularly effective for use in dentistry, though it is useful for a variety of other purposes, too.
