Definitions
- Composition based on stabilized trichlorethylene usable as raw material Composition based on stabilized trichlorethylene usable as raw material.
- HFA hydrofluoroalkanes
- This reaction can be carried out either in the liquid phase in the presence of catalysts such as SbC ⁇ at approximately 100 ° C, under a pressure of approximately 15 bars, or in the gas phase at 250 ° C in the presence of a chromium on alumina catalyst.
- 133a is an intermediate of choice for obtaining the 134a obtained according to the reaction CF3CH 2 CI + HF> CF3CH 2 F + HCI.
- This reaction can be carried out in the vapor phase at 350 ° C. under a pressure of 15 bars, in the presence of NiCr / Al 2 O 3 .
- TRI trichlorethylene
- CHCI 2 CHCI 2 and / or CH 2 CICCI 3 CHCI CCI 2 + HCI cracking
- aliphatic and cycloaliphatic amines such as triethylamine (US 1,925,602), diisopropylamine, triisopropylamine, cyclohexylamine (FR 2010281) which are HCI sensors; phenols such as p-tert-butylphenol, p-amylphenol, thymol (US 2,155,723) which are used as antioxidants; oxides such as butylene oxide (US 2,981,760) are also used to capture HCI. These compounds can be used alone or better in combination, (at a rate of a few tens of ppm).
- the Applicant has found that a TRI stabilized against acidity by a few ppm of diisopropylamine (DIPA) acidifies over time, especially in air.
- DIPA diisopropylamine
- the conversion of the TRI is equal to 99.4% after 2 hours and 99.3% after 100 hours, which indicates that it there is no deterioration of the catalyst.
- this procedure requires the use of two columns of zeolite: one in operation and one in regeneration and therefore a high investment in material (and of limited efficiency) for the productivity of an industrial unit .
- SbCI 5 which consists in using a TRI without stabilizer coming directly from manufacturing, that is to say a TRI which has not been stored. This procedure can only be carried out if there is a TRI preparation unit adjacent to an HFA production unit so as to avoid storage of said TRI.
- a subject of the invention is therefore the use of a composition based on trichlorethylene (TRI) stabilized as a raw material in particular for the synthesis of HFAs, characterized in that said composition consists of TRI, by at least one aliphatic amine used in weight quantities such that the weight content of total nitrogen is less than or equal to 3 ppm and, preferably between 1 ppm and 2.5 ppm, and with at least one phenol used in weight quantities at least equal to 3 ppm and, preferably between 5 ppm and 10 ppm.
- TRI trichlorethylene
- aliphatic amines which can be used according to the present invention, mention will be made of triethylamine, diethylamine, diisopropylamine, triisopropylamine and diisobutylamine.
- the present invention relates more particularly to the use of diisopropylamine (or DIPA).
- phenols which can be used according to the present invention mention will be made of paratertiobutylphenol, paratertioamylphenol, thymol (5-methyl-2-isopropyl-1-phenol).
- the present invention particularly relates to the use of thymol.
- an amount by weight of aliphatic amine will be used which makes it possible to obtain a weight content of total nitrogen less than or equal to 3 ppm.
- the composition according to the invention can be prepared by simple mixing of the compounds with freshly prepared trichlorethylene. This mixing can be carried out on an unstabilized TRI storage tank or more particularly in line at the outlet of the distillation column.
- composition according to the invention can be used very particularly for the preparation of HFAs such as 134a from 133a.
- the TRI used is obtained by pyrolysis at approximately 500 ° C. of tetrachloroethanes (sym. And dissym.). After separation of the HCl formed, the TRI is separated from the tetrachloroethones, washed and neutralized. It is then dried by distillation.
- Different compositions of stabilized TRI are prepared by adding the following stabilizers: thymol, diisopropylamine (DIPA), in proportions as indicated in table 1 to a TRI leaving directly from the distillation column. Aging tests are then carried out in air or under nitrogen at 40 ° C. of compositions 2 to 5 and of unstabilized TRI. To do this, hermetically closed 2 I glass vials containing 2 kg of product to be tested in air or under nitrogen are placed in an oven maintained at 40 ° C.
- DIPA diisopropylamine
- the pH is measured initially and after 75 days will be known for the non-stabilized TRI, where the pH is measured after 30 days.
- the pH is measured on the aqueous extract of a sample of the TRI composition mixed with water according to a TRI / water ratio of 1/1.
- composition 5 The synthesis of 134a is carried out using composition 5, according to the reactions:
- Step 1 / is carried out in the liquid phase in the presence of SbC 4 as a catalyst at approximately 100 ° C. under a pressure of 15 bars.
- Step 2 / is carried out in the vapor phase at 350 ° C. at 15 bars in the presence of a Ni / Cr catalyst on alumina.
