The present invention relates to a method for exchanging heat with an object said method comprising using a heat transfer fluid wherein said heat transfer fluid comprises one or more chemical compounds having the general formula (I) wherein: —Rcan be any C-Cfluorinated linear or branched carbon chain which can be partially or fully fluorinated, and can comprise O or S atoms, —X, Y and Z can be independently selected from halogens or hydrogen, with the provision that at least one of X, Y or Z is a halogen.

Heat exchange method using fluorinated compounds having a low GWP

The invention pertains to a multi-step process for making polyfunctional aromatic compounds comprising two phenyl rings bearing reactive groups susceptible of polycondensation reaction to provide polycondensed polymers, said method using economic raw materials, and possessing high selectivity and overall yield.

Method of making perfluorocyclobutane-containing monomer

A method for the manufacture of perfluorinated compounds is herein disclosed. In particular, the method is useful for the manufacture of perfluorooxyalkyl carboxylic acid salts which can be used as surfactants. The method envisages the fluorination or a fluoroformate of an alcohol comprising a &#x2014;CHOCH-moiety at a temperature equal to or higher than 20&#xb0; C. and allows obtaining high yields and selectivity.

Method for the manufacture of fluorinated compounds

The present invention relates to processes for the manufacture of 1,2,3,4-tetrachloro-hexafluoro-butane in a microreactor.

Processes for the synthesis of 1,2,3,4-tetrachloro-hexafluoro-butane

The invention relates to a process for the manufacture of a-iodoperfluoroalkanes and &#x3b1;,&#x3c9;-diiodoperfluoroalkanes of general formula: (1) A(CF)1, wherein: A is selected from F, CFand I and n is an integer equal to or higher than 1, with the proviso that, when A is F, n is an integer higher than 1 said process comprising heating a mixture [mixture (M1)] containing: &#x2014;a compound selected from I, CFI, CFCFI and CFI; &#x2014;TFE; &#x2014;and COat definite temperatures and concentrations of CO.

Process for the manufacture of &#x3b1;-iodoperfluoroalkanes and &#x3b1;,&#x3c9;-diiodoperfluoroalkanes

A trifluoroethylene composition which is safe to handle and which can be safely stored and transported at pressures of up to 5.00 MPa. The composition comprises trifluoroethylene and HCl in a molar ratio trifluoroethylene:HCl from 10:90 to 63:37. When the composition is a compressed gas it has a pressure of from 0.50 to 5.00 MPa.
