- the use of technical textiles thus functionalized makes it possible to retain the metallic trace elements such as cadmium, chromium, lead, copper, zinc, mercury, nickel, etc., present in an aqueous medium.
- technical textile can denote a fabric, non-woven, cord, braid, etc., made up of fibers called technical fibers, having characteristics chosen for one or more well-defined applications (water pollution control for example) .
- the fibers can be, for example, carbon, glass, polyester, polypropylene, aramid, polyethylene fibers.
- EXAMPLES 1 Preparation of acrylic acid from ⁇ -propiolactone according to the process of the invention
- the various reagents and solvents used in the process of the invention and in the examples ( ⁇ -propiolactone, the catalyst, etc. ) are, in general, commercial compounds or can be prepared by any process known to those skilled in the art. 1. Under an inert atmosphere or in air, the catalyst (x mol%), the ⁇ -propiolactone (x 'mol.L -1 ) and the solvent (x''mL) are introduced into an NMR tube.
- an internal standard can be added.
- the order of introduction of the reagent, solvent, internal standard or catalyst has no influence on the reaction.
- the NMR tube is then placed at a temperature between 15 and 80 ° C. 3.
- the conversion of ⁇ -propiolactone and the yield of acrylic acid can be followed by 1 H NMR (Bruker Avance Neo 400 MHz) or GC-MS (Shimadzu GCMS-QP2010 Ultra).
- the solvents and the various reagents used in the process of the invention are, in general, commercial compounds or can be prepared by any process known to those skilled in the art. Non-anhydrous solvents can be used.
- Example 2 Potassium iodide (4.1 mg, 0.025 mmol, 0.05 eq), ⁇ -propiolactone (31 ⁇ L, 0.500 mmol, 1 eq) and acetone-d 6 (500 ⁇ L) are added in a sealed tube. Finally, mesitylene (14 ⁇ L, 0.100 mmol, 0.1 eq) is added as an internal standard. The reaction is stirred for 16 hours at 45 ° C.
- Example 3 Potassium iodide (1.0 mg, 0.006 mmol, 0.05 eq), ⁇ -propiolactone (7.75 ⁇ L, 0.125 mmol, 1 eq) and acetone-d 6 (500 ⁇ L) are added in a sealed tube.
- mesitylene (3.5 ⁇ L, 0.025 mmol, 0.1 eq) is added as an internal standard. The reaction is stirred for 16 hours at 45 ° C.
- Example 4 Potassium iodide (4.1 mg, 0.025 mmol, 0.05 eq), crown ether 18-c-6 (6.6 mg, 0.025 mmol, 0.05 eq), ⁇ - propiolactone (31 ⁇ L, 0.500 mmol, 1 eq.) and acetone-d 6 (500 ⁇ L) are added in a sealed tube. Finally, mesitylene (14 ⁇ L, 0.100 mmol, 0.1 eq) is added as an internal standard. The reaction is stirred for 16 hours at 45 ° C.
- Example 5 Potassium iodide (41 mg, 0.25 mmol, 0.05 eq), ⁇ -propiolactone (310 ⁇ L, 5 mmol, 1 eq) and acetone-d6 (5 mL) are added to a single-neck balloon. Finally, mesitylene (14 ⁇ L, 0.100 mmol, 0.1 eq) is added as an internal standard. The reaction is stirred for 10 hours at 45 ° C. for a conversion of 99% with a selectivity of 73%. 2. Influence of the various parameters on the production of acrylic acid 2.1. Solvent test The influence of the solvent on the production of acrylic acid was studied.
