Process for producing carboxylic acid chloride. |
摘要 |
<p>Disclosed is a process for producing a carboxylic acid chloride by reacting phosgene with a carboxylic acid or an anhydride thereof, which comprises effecting the reaction in the presence of a homopolymer or copolymer of a monomer represented by formula (I) or (II) below, a copolymer of the monomers represented by formulae (I) and (II) below, or a copolymer of at least one monomer selected from the group sensisting of the monomers represented by formulae (I) and (II) below with another monomer copolymerizable therewith: CH2=CHNR<1>COR<2> (I> CH2=CR<3>CONR<4>R<5> (II). In these formulae R<1>, R<2>, and R<4> each represents an alkyl group containing from 1 to 3 carbon atoms, or an alkylene group containing from 3 to 5 carbon atoms provided that R<1> with R<2>, and R<4> with R<5> may each combine to form a ring structure through >N-CO- or >N- in the molecule; R<3> and R<5> each represents a hydrogen atom or an alkyl group containing from 1 to 3 carbon atoms; and the alkyl groups and alkylene groups may have substituents which are inactive under the polymerization and chlorination reaction conditions.</p> |
