| 20100174109 | METHOD FOR PRODUCING ETHYLENICALLY UNSATURATED GROUP-CONTAINING ISOCYANATE COMPOUND HAVING ETHER BOND - To provide a method for producing an ethylenically unsaturated group-containing isocyanate compound having an ether bond under such conditions that the ether bond is unlikely to be cleaved and the polymerization of an unsaturated group can be suppressed. The method for producing an ethylenically unsaturated group-containing isocyanate compound having an ether bond of the present invention is a method for producing an ethylenically unsaturated double bond-containing isocyanate compound from an amino alcohol having an ether bond and is characterized in that a reaction solvent in which the solubility of hydrogen chloride is 0.1 mole percent or less at 25° C. is used. | 07-08-2010 |
| 20110021808 | PROCESS FOR UNSATURATED QUATERNARY AMMONIUM SALT - An unsaturated quaternary ammonium salt is produced by a process that includes reacting methyl chloride in a first vessel with a stoichiometric excess of an unsaturated tertiary amine in the presence of water to form a reaction mixture that includes the unsaturated quaternary ammonium salt and residual unsaturated tertiary amine. The reaction mixture is transferred to a second vessel and phase separated to yield a first fraction in which the unsaturated quaternary ammonium salt is concentrated, and a second fraction in which the residual unsaturated tertiary amine is concentrated. At least a portion of the second fraction is recycled from the second vessel to the first vessel for use in the reaction with methyl chloride. The process, which is preferably operated continuously, allows the use of reduced reaction pressures compared to processes utilizing a stoichiometric excess of methyl chloride, and it also reduces or eliminates the problems associated with recycling methyl chloride and removing methyl chloride from the unsaturated quaternary ammonium salt product. | 01-27-2011 |
| 20110178327 | CONTINUOUS PRODUCTION OF DMAEA QUATERNARY SALTS - The invention provides a method of continuously producing high quality quaternized N,N-dialkylaminoethyl (meth)acrylates (DMAEA.MCQ) that has a long shelf life and which is stable in water. The method involves placing starting materials into a continuously stirred tank reactor in the presence of less than 6% water. This low amount of water causes two liquid phases to form and prevents unwanted side reactions. The denser liquid phase contains DMAEA.MCQ and the lighter phase contains the starting materials. Liquid from the denser phase is removed from a position where little of the lighter phase has been mixed in. The removed liquid then has any last traces of the starting materials reacted into DMAEA.MCQ and strips away any starting materials with a gas flow. The resulting liquid is high purity DMAEA.MCQ. Water can then safely be added to ease in the transport and use of the produced DMAEA.MCQ. | 07-21-2011 |

The invention also relates to the isocyanate obtainable by such a process. | 01-24-2013 |
| 20140046091 | Ester-Based Reactive Plasticizer For Plastic Bonded Explosives - Disclosed is an energetic reactive plasticizer for a plastic bonded explosive (PBX), and specifically an energetic reactive plasticizer for PBX which has high performance and insensitiveness without a plasticizer leak by being bonded with a polymer binder for a plastic bonded explosive. | 02-13-2014 |
| 20140303397 | VINYL MONOMERS HAVING CHELATING FUNCTIONALITY - The present invention provides novel polymerizable monomers having chelating functionality and processes to make them. In particular, the novel monomers are ethylenically unsaturated aminocarboxylates and are prepared by reacting ethylenediamine triacetic acid or its salt with an ethylenically unsaturated monomer. The ethyleneically unsaturated monomer may be a polymerizable vinyl monomer selected from (o-, p-, m-)DVBMO, allyl glycidyl ether, and glycidyl (meth)acrylate. | 10-09-2014 |
