Definitions
- the present invention relates to a methyl methacrylate derived from biomass, to a process for the manufacture thereof, to the uses of this methyl methacrylate as well as to its polymers.
- Methyl methacrylate is the starting material for many polymerization or copolymerization reactions.
- PMMA poly (methyl methacrylate)
- PMMA poly (methyl methacrylate)
- ALTUGLAS® poly (methyl methacrylate)
- PLEXIGLAS® poly (methyl methacrylate)
- It is in the form of powders, granules or plates, the powders or granules used to mold various articles, such as articles for the automobile, household and office items, and the plates found use in the signs and displays, in the fields of transportation, building, lighting and sanitary, as noise barriers, for works of art, flat screens, etc.
- Methyl methacrylate is also the starting material for the organic synthesis of higher methacrylates, which, like it, are used in the preparation of acrylic emulsions and acrylic resins, serve as additives for polyvinyl chloride, enter As comonomers in the manufacture of many copolymers such as methyl methacrylate-butadiene-styrene copolymers, serve as additives for lubricants, and have many other applications among which one could mention medical prostheses, flocculants, products of maintenance, etc.
- Acrylic emulsions and resins have applications in the fields of paints, adhesives, paper, textile, inks, etc.
- Acrylic resins are also used for the manufacture of plates, having the same applications as PMMA.
- Methyl methacrylate can be obtained in a variety of ways, the most common route being acetone cyanohydrin (Engineering Techniques, Process Engineering, J 6400 1-6).
- acetone is reacted with hydrogen cyanide in basic catalysis to form acetone cyanohydrin. It is reacted with sulfuric acid, which gives rise by a strongly exothermic reaction to the formation of ⁇ -oxyisobutyramide monosulfate, which is converted into sulfuric methacrylamide. The latter is then hydrolyzed and esterified with methanol to form the desired methyl methacrylate, as well as the ammonium acid sulfate, the latter being recovered to regenerate the sulfuric acid.
- Acetone is the co-product of the synthesis of phenol obtained by decomposition of cumene hydroperoxide.
- Hydrogen cyanide is obtained either as a by-product of the synthesis of acrylonitrile by ammoxidation of propylene, or by the reaction of methane or methanol with ammonia.
- Ammonia was obtained by reaction of nitrogen and hydrogen, the latter itself being obtained generally by steam reforming of methane and / or by reaction of gas with water “Water Gas Shift" of the synthesis gas .
- the raw materials used for the synthesis of methyl methacrylate are mainly of petroleum origin or of synthetic origin. This process thus has many sources of CO2 emissions, which have been reported in the literature to be 5600g / kg of PMMA (Catalysis Today 99, 2005, 5-14) and therefore contribute to the increase of the greenhouse effect. Given the dwindling global oil reserves, the source of these raw materials will gradually be exhausted. Raw materials from biomass are renewable and have a reduced impact on the environment. They do not require all the refining steps, very expensive in energy, petroleum products. CO2 production is reduced so that they contribute less to global warming. Especially for its growth, the plant has consumed atmospheric CO2 at a rate of 44g of CO2 per mole of carbon (or for 12 g of carbon). So the use of a renewable source begins by decreasing the amount of atmospheric CO2. Vegetable materials have the advantage of being able to be grown in large quantities, depending on the demand, on most of the terrestrial globe including algae and microalgae in the marine environment.
- Biomass is the raw material of plant or animal origin naturally produced. This plant material is characterized by the fact that the plant for its growth has consumed atmospheric CO2 while producing oxygen. The animals for their growth consumed this vegetable raw material and thus assimilated carbon derived from atmospheric CO2.
- the purpose of the present invention is therefore to respond to certain sustainable development concerns and to propose a methyl methacrylate whose at least a part of its carbons is of renewable origin, or bioresourced.
- renewable or bioresourced raw material is a natural resource, animal or plant, 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.
- biobased raw materials contain 14 C in the same proportions as atmospheric CO2. 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.In the environment, 14 C exists in two main forms: in mineral form, that is to say gas carbon dioxide (CO2), and in organic form, that is to say of carbon integrated in organic molecules.
- CO2 gas carbon dioxide
- the 14 C / 12 C ratio is kept constant by the metabolism because the carbon is continuously exchanged with the environment.
- the proportion of 14 C is constant in the atmosphere, it is the same in the body, as long as it is alive, since it absorbs this 14 C as it absorbs 12 C.
- the average ratio of 14 C / 12 C is equal to l, 2xl ⁇ ⁇ 12 for a bioresourced material, while a fossil raw material (for example from oil, natural gas or coal) has a zero ratio.
- Carbon 14 is derived from the bombardment of atmospheric nitrogen (14), and spontaneously oxidizes with oxygen in the air to give CO2.
- the content of 14 C02 has increased as a result of explosions atmospheric nuclear power, and then continued to decline after stopping these tests.
- 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 (each gram of carbon in a living being contains enough 14 C isotopes to give 13.6 disintegrations per minute) and the number of such atoms in a sample decreases over time (t ) according to the law :
- n is the number of 14 C atoms remaining at the end of time t
- the disintegration constant or radioactive constant
- the half-life of 14 C is 5730 years. In 50 000 years the 14 C content is less than 0.2% of the initial content and therefore becomes difficult to detect. Petroleum products, or natural gas or coal therefore do not contain 14 C. Given the half-life (Ti / 2 ) of 14 C, the 14 C content is substantially constant since the extraction of the materials. first bioressourced, up to the manufacture of methyl methacrylate according to the invention and even until the end of its use.
- the 14 C content of a "biomaterial” can be deduced from measurements carried out for example by the following techniques: by liquid scintillation spectrometry: this method consists in counting 'Beta' particles resulting from the decay of 14 C. Beta radiation from a sample of known mass (number of known carbon atoms) for a certain time. This 'radioactivity' is proportional to the number of 14 C atoms, which can be determined.
- the 14 C present in the sample emits ⁇ - radiation, which, in contact with the scintillating liquid (scintillator), give rise to photons. These photons have different energies
- the analysis relates to the CO2 previously produced by combustion of the carbon sample in an absorbing solution appropriate, or on benzene after prior conversion of the carbon sample to benzene.
- mass spectrometry the sample is reduced to graphite or gaseous CO2, analyzed in a mass spectrometer. This technique uses an accelerator and a mass spectrometer to separate 14 C ions and 12 C and thus determine the ratio of the two isotopes.
- the measurement method preferably used is mass spectrometry described in standard ASTM D6866-06 ("accelerator mass spectroscopy").
- the methyl methacrylate of the present invention contains organic carbon from biomass determined according to ASTM D6866.
- the present invention therefore firstly relates to a methyl methacrylate characterized in that it contains from 0.2xl0 "10 % to l, 2xl ⁇ " 10 % by weight of 14 C on the total mass of carbon according to ASTM D6866 preferably from 0.4 ⁇ 10 -10 % to 1.2 ⁇ 10 -10 % by weight of 14 C, more particularly from 0.6 ⁇ 10 -10 % to 1.1 ⁇ 10 -10 % by weight of 14 C, still more preferably from 0 to 10 % by weight. 8xl0 ⁇ 10 % to l, 2xl ⁇ ⁇ 10 % by weight of 14 C.
