Preparation
Methyl hexahydrophthalic anhydride is produced from methyl tetrahydrophthalic anhydride by catalytic hydrogenation. It is a high-performance product among acid anhydride-type solidifying agent.
Flammability and Explosibility
Nonflammable
storage
MHHPA must be stored away from open flames or other potential ignition sources, and should be protected from moisture, because it easy crystallizes when it's in contact with the humidity of the air. When some crystallization occurs, check the properties before reusing.
Check Digit Verification of cas no
The CAS Registry Mumber 25550-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25550-51:
(7*2)+(6*5)+(5*5)+(4*5)+(3*0)+(2*5)+(1*1)=100
100 % 10 = 0
So 25550-51-0 is a valid CAS Registry Number.
