25293-64-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25293-64-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,2,9 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25293-64:
(7*2)+(6*5)+(5*2)+(4*9)+(3*3)+(2*6)+(1*4)=115
115 % 10 = 5
So 25293-64-5 is a valid CAS Registry Number.

Preparation method of 4,5-epoxytetrahydrophthalate glycidyl ester

-

Paragraph 0021-0052, (2022/01/10)

The present invention provides a method for preparing 4,5-epoxytetrahydrophthalate glycidyl ester. The present invention by taking acetic anhydride as raw material, adding 62.5% ~ 64.7% of hydrogen peroxide and a certain amount of acidic catalyst oxidation to generate peracetic acid, and then the tetrahydrophthalic acid glycidyl ester and the reaction of peracetic acid to obtain epoxy reaction, and then through a series of post-treatments to give 4,5-epoxytetrahydrophthalic acid glycidyl ester. The preparation method of the present invention is compared with the traditional process, which greatly reduces the concentration of hydrogen peroxide, thereby solving the problem that high concentration of hydrogen peroxide in the traditional process is easy to explode during storage, transportation and use, and also reduces the cost of raw materials. Compared with the prior art, the epoxy value of 4,5-epoxytetrahydrothphthalate glycidyl ester products prepared by the present invention is also higher.
