64741-66-8 Usage
Description
Naphtha (petroleum), light alkylate is a light petroleum product, the word comes from Persian, which refers to volatile petroleum products, generally refers to the fraction of 30 ~ 220 ℃. Since the 1960s, with the development of the petrochemical industry, naphtha has become an important raw material for the production of ethylene, propylene, benzene, toluene and xylene by tube furnace cracking.
Chemical Properties
Naphtha (petroleum), light alkylate is colorless or light yellow liquid. Coking aromatic hydrocarbon mixture obtained by fractional distillation of coal tar light oil. The boiling range is 120 ~ 200 ℃, mainly composed of toluene, xylene isomer lookchem, ethylbenzene, cumene, etc. The relative density is (20℃/4℃) 0.85～0.95, the flash point is 35～38℃, and the chemical properties are similar to toluene and xylene.
Uses
Naphtha is mainly used as raw material for cracking, catalytic reforming and ammonia production, and can also be used as chemical raw material and general solvent.
Flammability and Explosibility
Extremelyflammable
Check Digit Verification of cas no
The CAS Registry Mumber 64741-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,4 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 64741-66:
(7*6)+(6*4)+(5*7)+(4*4)+(3*1)+(2*6)+(1*6)=138
138 % 10 = 8
So 64741-66-8 is a valid CAS Registry Number.
