Usage

General Description

1,1,1,3-Tetrachlorotetrafluoropropane, also known as CFC-113a, is a chemical compound consisting of four chlorine atoms and four fluorine atoms attached to a central carbon atom. It is a colorless, odorless gas with a high boiling point, making it suitable for use as a refrigerant and propellant. However, it has been found to have a detrimental impact on the ozone layer and contributes to the depletion of ozone in the atmosphere. As a result, its production and use have been restricted or banned in many countries under the Montreal Protocol on Substances that Deplete the Ozone Layer. Despite its utility as a refrigerant, its environmental impact has led to the search for alternative compounds with less damaging effects on the ozone layer.

NOUVELLE METHODE de DETERMINATION des INDICES de REFRACTION d'ALCANES PERHALOGENES

We propose a new formula such as (*) in order to calculate the refractive index (n) of perhalogenated alkanes containing Ni atoms i(C,F,Cl, or Br), at a given temperature.The contributions Ki of each element are determined at different temperatures.This method which has been tested on a series of compounds whose experimental values of the refractive index are given is the literature, leads to results which are much nearer reality than those given by different methods known so far.

PROCESS FOR PRODUCTION OF 2,3,3,3-TETRAFLUOROPROPENE

The present invention provides a process for producing 2,3,3,3-tetrafluoropropene including the following reaction steps: (i) reducing a halogenated fluoropropane represented by formula (1): ACF2CF2CH2FyAz, wherein A is Cl, Br, or I; x is an integer from 0 to 2; y and z are each an integer from 0 to 3; and the total number of x, y, and z is 3, to produce a 1-halogenated-1,1,2,2-tetrafluoropropane represented by formula (2): ACF2CF2CH3; and (ii) contacting the 1-halogenated-1,1,2,2-tetrafluoropropane obtained in step (i) with a catalyst in a gas phase to produce 2,3,3,3-tetrafluoropropene. According to the invention, 2,3,3,3-tetrafluoropropene (HFO-1234yf) can be produced in a high yield, using inexpensive starting materials.

19F nuclear magnetic resonance studies of halogenated propanes

The relationship between 19F chemical shifts in halogenated propanes and their structures are elucidated using MNDO calculations to determine the population of rotamers.The pairs of atom gauche to a fluorine atom and van der Waals interaction between the two terminal substituents are responsible for the 19F chemical shifts.The differences among chemical shifts in diastereomers are also discussed in terms of the conformation of molecule.
