628-08-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 628-08-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 628-08:
(5*6)+(4*2)+(3*8)+(2*0)+(1*8)=70
70 % 10 = 0
So 628-08-0 is a valid CAS Registry Number.

INTEGRATED PROCESS TO PRODUCE DERIVATIVES OF BUTADIENE ADDITION PRODUCTS

-

Page/Page column 37-39, (2008/06/13)

An integrated chemical process to form derivatives of butadiene addition products comprises forming an addition product of butadiene and a selected carboxylic acid, alcohol, or glycol, to form a reaction mixture containing at least a crotyl addition produ

PROCESS FOR MAKING BUTENYL ESTERS FROM BUTADIENE

-

Page/Page column 9-13, (2008/06/13)

A process for making a butenyl ester from butadiene by reacting butadiene or a hydrocarbon fraction containing butadiene with a saturated aliphatic monocarboxylic acid, wherein the catalyst is rhenium (VII) oxide or an organic sulphonic acid containing at least (2) sulphonic acid groups per molecule wherein the ratio of the number of carbon atoms to the number of sulphonic acid groups in the organic sulphonic acid is in the range 1 : 1 to 1 : 0.15. Preferred catalysts are organic disulphonic acids for example ethane-1,2-disulphonic acid. The process can be used for making unsaturated esters, or, by hydrogenation of the product, for making saturated esters such as for example butyl acetate. Catalyst can be purified and recycled to the reactor.
