Uses

Chloromaleic Acid Anhydride is a reagent in metal hydride reduction of unsymmetically substituted cyclic anhydrides.

Check Digit Verification of cas no

The CAS Registry Mumber 96-02-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 6 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 96-02:
(4*9)+(3*6)+(2*0)+(1*2)=56
56 % 10 = 6
So 96-02-6 is a valid CAS Registry Number.

Method for preparing 2-chloromaleic anhydride

-

Paragraph 0030-0037, (2021/02/06)

The invention relates to the technical field of organic synthesis, in particular to a method for preparing 2-chloromaleic anhydride, which comprises the following steps of adding maleic anhydride intoa reaction bottle, heating until the solid is molten, adding ferric trichloride, and pumping the reaction solution into a mixing module by using a pump, introducing chlorine into the mixing module, heating the micro-channel reaction module, and enabling reaction liquid in the mixing module to pass through the micro-channel reaction module at a certain flow rate, then connecting a micro-reactor with a fixed bed, heating the micro-reactor, introducing the reaction liquid passing through the micro-channel reactor into the fixed bed micro-reactor for reaction by adopting a mixed catalyst consisting of barium chloride and activated carbon, introducing nitrogen at a certain rate, taking away hydrogen chloride gas generated by the reaction, and collecting the reaction liquid, and distilling to obtain the 2-chloromaleic anhydride. The mixed catalyst composed of barium chloride and activated carbon is adopted, the reaction speed is high, the product yield and purity are high, and the requirement for equipment is lowered.

CRYSTAL STRUCTURE OF N-(2,6-DIMETHYLPHENYL)CHLOROMALEINIMIDE

Vrabel, Viktor,Kelloe, Eleonora,Lokaj, Jan,Konecny, Vaclav

, p. 2408 - 2414 (2007/10/02)

The crystal structure of N-(2,6-dimethylphenyl)chloromaleinimide solved by the heavy atom method was refined by the 9*9 block-diagonal matrix least squares method to a final R value 0.08 for 1147 observed diffractions.The compound crystallizes in the orthorhombic system with Pbca group and lattice parameters a=13.622(4), b=13.483(7), c=12.768(6) Angstroem, Z=8.Monomeric units, between which interactions of type Cl...H-C and O...H-C occured, formed the crystal structure.Both moieties of the molecule, i.e. the phenyl and the five-membered maleinimide rings were foundto be virtually planar and the central planes intersecting these rings form an angle 78.3 deg.
