Benzene carboxylic acid (BCAs) are common and useful chemical blocks, which can be derived from the abundant low rank coals (LRCs) via oxidative degradation. In this work, we proposed a novel strategy to utilize BCAs as raw materials to prepare catalysts with transition metal zirconium, and ...

1. A process for preparing a hydroxyalkyl (meth)acrylate which comprises reacting at least one compound A which contains at least one epoxide group with at least one compound B which contains at least one carboxylic acid group, wherein A and/or B also contains at least one (meth)acrylate ...
wherein R, R1, R2 and R3 may be the same or different from each other and denote hydrogen, C1-C4-alkyl, C1-C4-alkoxy, C1-C4-alkoxycarbonyl, chlorine, bromine, nitro or sulfo and X denotes oxygen, sulfur or NH, which comprises reacting a (4-chloromethyl)-iminobenzoic acid alkyl ester...
Novel compounds of the Formula I, in which R1 represents a group of the formula -NHR, wherein R represents a hydrogen atom or an acyl group which is derived from carbonic acid or a monoester of carbonic acid, benzoic acid substituted by a halogen atom or hydroxy group, or a monocarboxyli...
(4-chloromethyl)-iminobenzoic acid alkyl ester of the formula wherein R denotes C1-C4-alkyl or C1-C4-alkoxyethyl, or HCl salts thereof, with o-aminophenol, o-aminothiophenol or o-phenylene diamine and reacting the resulting 2-benz-ox(-thi,-imid)-azolyl-4-chloromethyl-benzenes with ...
The latter is chlorinated in the side chains under free-radical conditions to give 2,4-dichloro-5-fluoro-3-dichloromethyl-1-trichloromethylbenzene (VI). The latter is hydrolyzed via 2,4-dichloro-5-fluoro-3-dichloromethylbenzoic acid (V), which can be isolated if necessary, to give 2,4-...
