64712-27-2 Usage
Uses
Used in Refrigeration Industry:
1,1-DICHLORO-1,3,3,3-TETRAFLUOROPROPANE is used as a refrigerant for its thermodynamic properties, which allow for efficient cooling and heating in various refrigeration systems.
Used in Foam Plastics Production:
1,1-DICHLORO-1,3,3,3-TETRAFLUOROPROPANE is used as a blowing agent in the production of foam plastics, providing the necessary expansion and formation of the plastic material.
Environmental and Health Concerns:
1,1-DICHLORO-1,3,3,3-TETRAFLUOROPROPANE is considered an ozone-depleting substance and a greenhouse gas, contributing to the depletion of the ozone layer and global warming. As a result, its production and use are being phased out and replaced by more environmentally friendly alternatives.
Regulatory Restrictions:
Due to the environmental and health hazards associated with 1,1-DICHLORO-1,3,3,3-TETRAFLUOROPROPANE, its production and use are subject to restrictions in many countries as part of the Montreal Protocol and other environmental regulations. This has led to a gradual shift towards the adoption of alternative substances with lower environmental impacts.
Check Digit Verification of cas no
The CAS Registry Mumber 64712-27-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,1 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64712-27:
(7*6)+(6*4)+(5*7)+(4*1)+(3*2)+(2*2)+(1*7)=122
122 % 10 = 2
So 64712-27-2 is a valid CAS Registry Number.

Page/Page column 3-4, (2008/06/13)
Carboxylic acids can be prepared by reacting compounds comprising a -CCl 2 F group, a CCIF 2 group or a CCl 3 group with sulfur trioxide and sulfuric acid. The reaction is especially suitable for the preparation of 3,3,3-trifluoropropionic acid from CF 3 -CH 2 -CCl 2 F, CF 3 -CH 2 -CCIF 2 , CF 3 -CH 2 -CCl 3 or a mixture of one or two thereof as starting material. Usually, oleum is used as the source for sulfur trioxide. In a preferred embodiment, the starting material comprises CF 3 -CH 2 -CCl 2 F and/or CF 3 -CH 2 -CCIF 2 which is or are prepared in a fluorination reaction between CCl 3 -CH 2 -CCl 3 and HF. As a source for CCl 3 -CH 2 -CCl 2 , the product of the reaction between CH 2 =CCl 2 and CCl 4 is advantageously used.
