- Vinyl chloride monomer is well known for its use as a monomer in (co) polymers.
- vinyl chloride can be used for the synthesis of polyvinyl chloride.
- One of the problems posed by the vinyl chloride monomer synthesis processes of the prior art is that it is made from raw materials of non-renewable fossil (petroleum) origin, in particular ethylene.
- ethylene non-renewable fossil
- the resources of these raw materials are limited, the extraction of oil requires to dig deeper and deeper and under ever more difficult technical conditions requiring sophisticated equipment and the implementation of ever more energy intensive processes. These constraints have a direct consequence on the manufacturing cost of ethylene and thus on the manufacturing cost of vinyl chloride monomer.
- the inventors of the present application have implemented a process for the industrial manufacture of vinyl chloride monomer from renewable raw materials.
- the process according to the invention makes it possible to dispense at least partly from raw materials of fossil origin and to replace them with renewable raw materials.
- the monomeric vinyl chloride obtained according to the process according to the invention is of such quality that it can be used in all applications in which it is known to use vinyl chloride monomer.
- the subject of the invention is thus a process for the manufacture of vinyl chloride monomer comprising the following steps: a) preparation of acetylene from one or more renewable raw materials, and then b) reaction of acetylene with dichloride hydrogen to form vinyl chloride monomer.
- the subject of the invention is also the vinyl chloride monomer in which at least a portion of the carbon atoms is of renewable origin, as well as the vinyl chloride monomer obtainable by the process according to the invention.
- the subject of the invention is also a composition comprising said vinyl chloride, as well as the use of said monomeric vinyl chloride.
- renewable raw material is a natural resource, for example animal or vegetable, whose stock can be reconstituted over a short period on a human scale. In particular, this stock must be renewed as quickly as it is consumed. For example, vegetable matter has the advantage of being able to be cultivated without their consumption leading to an apparent decrease in natural resources.
- renewable raw materials contain 14 C. All carbon samples taken from living organisms (animals or plants) are in fact a mixture of 3 isotopes: 12 C (representing about 98.892%), 13 C (about 1, 108%) and 14 C (traces: 1, 2.10 ⁇ 10 %). The 14 C / 12 C ratio of living tissues is identical to that of the atmosphere.
- 14 C exists in two main forms: in the form of carbon dioxide (CO 2 ), and in organic form, that is to say of carbon integrated in organic molecules.
- CO 2 carbon dioxide
- organic form that is to say of carbon integrated in organic molecules.
- the proportion of 14 C being constant in the atmosphere, it is the same in the body, as long as it is alive, since it absorbs this 14 C in the same way as the 12 C ambient.
- the average ratio of 14 C / 12 C is equal to l, 2x l ⁇ ⁇ 12 .
- 12 C is stable, that is to say that the number of atoms of 12 C in a given sample is constant over time.
- 14 C is radioactive, the number of 14 C atoms in a sample decreases over time (t), its half - life being equal to 5730 years.

Therefore, the presence of 14 C in any material, whatever the quantity, gives an indication of the origin of the molecules constituting it, namely that they come from renewable raw materials and not from fossil materials .
- the amount of 14 C in a material can be determined by one of the methods described in ASTM D6866-06 (Standard
- This standard contains three methods for measuring organic carbon derived from renewable raw materials, referred to in English as "biobased carbon”.

- the electrodes are generally introduced gradually into the lime mix. renewable raw material (s) of which they cause the partial fusion and the mutual reaction.
- the electrodes are generally continuous, but may include a hollow zone for the injection of raw material fines from the supply or dedusting, which allows continuous introduction of raw materials directly into the reactor.
- the electrodes are generally supplied with three-phase alternating current, at a voltage of 100 to 250 V, with a current density of less than 10 A / cm 2 of electrode surface.
- the electricity consumption can be up to 3.30 kWh / kg of carbide.
- Calcium carbide is obtained in the molten state and is generally poured through orifices at the base of the furnace. It can be collected in ingot molds, where it cools for 1 to 2 hours before being demolded for later crushing and screening.
- the production of calcium carbide is accompanied by the release of a large amount of carbon monoxide, generally 400 Nm 3 / t. This gas contains on average 70% by volume of carbon monoxide, as well as dust. It can be used as fuel in ancillary installations.

- Wet generators are mainly used in the production of dissolved acetylene. Among these are the falling water carbide, water drop and contact devices.
- Dry generators are mainly used in large capacity installations.
- the water / calcium carbide weight ratio is generally about 1.1.
- Hydrolysis of calcium carbide to form acetylene generally comprises the steps described hereinafter.

- the cylinder is usually contained in a concentric envelope.
- the carbide is generally in the form of granules.
- the reactor is kept agitated to prevent calcium carbide grains from floating on the surface where they could overheat and ignite the acetylene.
- the water is then sprayed into said cylinder, generally within the inner shell.
- the formed acetylene is then directed from the conveyor to a scrubber and is again sprayed with water. This new water spray causes most of the solids carried by the gas. Any residual lime and any impurities in the carbide are usually driven by a conveyor screw to a tank.
- the acetylene is cooled to a temperature below 0 ° C., preferably between -5 ° C. and -15 ° C., more preferably of the order of -10 ° C., to condense the majority of the water .
- the acetylene is then purified by contact with sulfuric acid, preferably diluted, usually in a liquid-liquid absorber. Then the acetylene is again purified with sodium hypochlorite, usually prepared by the action of chlorine on the soda, to remove impurities.
- this first embodiment of the invention makes it possible to limit the formation of impurities.
- High purity acetylene can be obtained by using cellulose, straw, wood or lignin as a renewable raw material. To limit impurities, they can also be extracted directly from fresh biomass, rather than from charcoal, which has already evolved to a more thermodynamically stable stage.

- acetylene from one or more hydrocarbons is based on the thermodynamic properties of acetylene.
- the usual paraffins and olefins are more stable than acetylene at normal temperatures. As the temperature increases, the free energy of paraffins and olefins becomes positive, while that of acetylene decreases.
- acetylene is the most stable of the usual hydrocarbons. However, although it has the lowest free energy of hydrocarbons at this temperature, acetylene is unstable with respect to its elements C and H 2 . Since the activation energy of the acetylene formation reaction is greater than that of its decomposition reaction, more acetylene is produced as the reaction medium is heated more rapidly to a higher temperature.

- the cycle comprises four periods: a heating phase: the air enters the oven through one of the ends (right for example), warms through refractory bricks to a temperature generally between 980 and 1 100 0 C, and reached the fuel injection chamber. The combustion brings the temperature generally to 1200-1300 0 C.
