13288-70-5 Usage

Uses

Bis(4-hydroxy-3,5-dimethylphenyl) Sulfone is used in preparation and properties of novel alternating poly(aryl ether ketone).

Check Digit Verification of cas no

The CAS Registry Mumber 13288-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,8 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13288-70:
(7*1)+(6*3)+(5*2)+(4*8)+(3*8)+(2*7)+(1*0)=105
105 % 10 = 5
So 13288-70-5 is a valid CAS Registry Number.

Method for preparing aromatic bischloroformate compositions

-

, (2008/06/13)

Bischloroformate oligomer compositions are prepared by passing phosgene into a heterogeneous aqueous-organic mixture containing at least one dihydroxyaromatic compound, with simultaneous introduction of a base at a rate to maintain a specific pH range and to produce a specific volume ratio of aqueous to organic phase. By this method, it is possible to employ a minimum amount of phosgene. The reaction may be conducted batchwise or continuously. The bischloroformate composition may be employed for the preparation of cyclic polycarbonate oligomers or linear polycarbonate, and linear polycarbonate formation may be integrated with bischloroformate composition formation in a batch or continuous process.

Cyclic monocarbonate bishaloformates

-

, (2008/06/13)

Cyclic monocarbonate bischloroformates are prepared by the reaction of a carbonyl halide such as phosgene with a bridged substituted resorcinol or hydroquinone such as bis(2,4-dihydroxy-3-methylphenyl)methane or bis(2,5-dihydroxy-3,4,6-trimethylphenyl)methane in the presence of aqueous alkali metal hydroxide. The cyclic monocarbonate bischloroformates may be used for the preparation of linear or cyclic polycarbonates containing cyclic carbonate structural units, which may in turn be converted to crosslinked polycarbonates.
