Usage

Uses

Used in Aerosol Products:
1,1,1,2,4,4,4-Heptafluorobutane is used as a propellant in aerosol products such as air dusters and deodorants, providing a safe and effective means of dispensing these products.
Used in Refrigeration Systems:
As a refrigerant, 1,1,1,2,4,4,4-Heptafluorobutane is utilized in various cooling systems, including air conditioning and refrigeration units, due to its non-toxic and nonflammable properties.
Used in Fire Suppression Systems:
1,1,1,2,4,4,4-Heptafluorobutane is used as a fire suppressant due to its high heat capacity, which allows it to quickly extinguish flames and prevent re-ignition.
However, it is important to note that 1,1,1,2,4,4,4-Heptafluorobutane is a potent greenhouse gas with a high global warming potential. As a result, it is subject to regulation and phase-out in some countries due to environmental concerns.

Method for preparing E-1, 1, 1, 4, 4, 4-hexafluoro-2-butene by gas phase fluorination

The invention discloses a method for preparing E-1, 1, 1, 4, 4, 4-hexafluoro-2-butene by gas-phase fluorination. The method comprises the following steps: in the presence of a fluorination catalyst, carrying out fluorination reaction on tetrafluorobutane or tetrachlorobutane and hydrogen fluoride to obtain the E-1, 1, 1, 4, 4, 4-hexafluoro-2-butene. The method is mainly used for efficiently and continuously producing E-1, 1, 1, 4, 4, 4-hexafluoro-2-butene in a circulating manner.

PREPARATION OF HYDROFLUOROOLEFINS BY DEHYDROFLUORINATION

A dehydrofluorination process is disclosed for making hydrofluoroolefins of the structure RfCH═CHRf, wherein each Rf is independently a perfluoroalkyl group or a perfluoroalkyl group having a terminal hydrogen. The process involves reacting RfCH2CHFRf with a basic aqueous solution to produce a product mixture comprising RfCH═CHRf.

THE FLUORINATION OF BUTANE OVER COBALT TRIFLUORIDE

The fluorination of butane over cobalt trifluoride has given a complex mixture of partially fluorinated compounds: 51 of these have been identified, comprising over 99percent of the products.Most were polyfluor-butanes but 1-2percent were polyfluoro-2-methylpropanes.The reaction has no synthetic utility.There was some selectivity in the fluorination: secondary C-H was convertart byed into C-F more easily then primary, and the ease of replacement of a particular H was reduced by geminal vicinal fluorines.A computer model of the fluorination was only partially successful, perhaps because the fluorination proceeded in part by simple F for H replacement and in part via alkenes: the model only allowed for the former.

REACTION OF HYDROXY AND CARBONYL COMPOUNDS WITH SULFUR TETRAFLUORIDE. X. REACTION OF ALIPHATIC β-HYDROXYCARBOXYLIC ACIDS WITH SULFUR TETRAFLUORIDE

The reactions of 3-hydroxypropionic, d,l-3-hydroxybutyric, d,l-4,4,4-trifluoro-3-hydroxybutyric, and 4,4,4-trifluoro-3-trifluoromethyl-3-hydroxybutyric acids with sulfur tetrafluoride were investigated.It was shown that the electronic nature of the substituents at the β-carbon atom has a significant effect on the direction of the reactions of β-hydroxycarboxylic acids with sulfur tetrafluoride.

Reaction of aliphatic α-hydroxy carboxylic acids with sulfur tetrafluoride

Trifluoroalkyl fluorosulfites are mostly formed during the reaction of glycolic, d,l-lactic, and d,l-malic acids with sulfur tetrafluoride.Hydrolysis of the products gave the corresponding trifluoromethylcarbinols.
