Definitions
- the present invention relates to a process for the preparation of 1, 2-propanediol from glycerol.
- 1, 2-Propanediol is currently produced industrially from propylene oxide by water addition and used in a variety of applications, such. as a component of brake and hydraulic fluids, lubricants and antifreeze, in cosmetics, in the food industry and as a solvent for fats, oils, resins and dyes.
- Propylene oxide and thus also 1, 2-propanediol is currently produced entirely from fossil fuels.
- glycerol Due to the constant demand for the use of renewable raw materials and the rising crude and falling glycerol prices, there is a great need to use glycerol, which is a by-product in large quantities in biodiesel production, as a starting material for suitable chemical reactions on a large industrial scale.
- DE-A-4442 124 describes the catalytic hydrogenation of glycerol with a water content of up to 20% by weight to propylene glycol in a yield of 92%, as by-products n-propanol and lower alcohols are obtained.
- Complete conversion of glycerine is achieved through the use of a mixed catalyst of the metals cobalt, copper, manganese and molybdenum.
- the reaction conditions are in a pressure and temperature range of 100 to 700 bar and 180 to 270 0 C.
- Preferred hydrogenation conditions are 200 to 325 bar and 200 to 250 0 C.
- the disadvantage is that at lower pressures, the reaction of glycerol is incomplete, and increasingly form lower alcohols at higher pressures.
- US 4,642,394 describes a process for the catalytic hydrogenation of glycerol with a catalyst consisting of tungsten and a group VIII metal.
- the Reaction conditions range from 100 psi to 15,000 psi and 75 to 250 ° C. Preferred process conditions are 100 to 200 ° C and 200 to 10,000 psi.
- the reaction is carried out under basic conditions by the use of amines or amides as solvent. It is also possible to use metal hydroxides, metal carbonates or quaternary ammonium salts.
- the solvent is added in a concentration of 5 to 100 ml per gram of glycerol. Carbon monoxide is used to stabilize and activate the catalyst.
- EP-AO 523 015 describes the hydrogenation of glycerol over Cu / Zn catalysts, but using very dilute aqueous solutions (about 30% by weight of glycerol content) which are further diluted by the water of reaction formed. To obtain 1, 2-propanediol therefore a large amount of water must be distilled off from the product, which means a lot of energy and does not make the process economical. Furthermore, the process at relatively high pressures of preferably 100, - bar and high temperatures 230150-270 0 C. The conversion of glycerol is in the range of 8 to 100% at a selectivity to propylene glycol of 80 to 98%, as by-products of alcohols and ethylene glycol are formed.
- DE-A-43 02 464 describes a process in which glycerol is hydrogenated in a continuous mode over a fixed bed CuO / ZnO catalyst.
- a complete hydrogenation of glycerol is achieved at 200 0 C, as by-products low-level alcohols and relatively large amounts (5.4 wt .-%) of unknown substances are formed.
- Another disadvantage is the very high reaction pressure of 250 bar. At lower pressures (50-150 bar) and higher temperatures (240 ° C.), increasingly unknown substances (25-34% by weight) are formed, with the selectivity for 1,2-propanediol falling to 22-31% by weight ,
- 1, 2-propanediol can be prepared by hydrogenation of substantially pure glycerol on a copper oxide / zinc oxide catalyst in high yield and high selectivity.
- a selectivity to 1,2-propanediol of up to 98% is achieved with complete conversion of the glycerol, as by-products only monoethylene glycol (about 2%) and in a small amount of n-propanol are detectable.
- the invention relates to a process for the preparation of 1, 2-propanediol by reacting glycerol, which has a purity of at least 95 wt .-%, with hydrogen at a hydrogen pressure of 20 to 100 bar and a temperature of 180 to 24O 0 C. in the presence of a catalyst comprising 10 to 50% by weight of copper oxide and 50 to 90% by weight of zinc oxide in an autoclave.
- the catalyst used in the process according to the invention is preferably free of carrier material and preferably contains 30-35% by weight of copper oxide, and preferably 65-70% by weight of zinc oxide. In a further preferred
- Embodiment copper oxide and zinc oxide add up to 100 wt .-%.
- a reduction and activation of the catalyst before the reaction can proceed at 170-240 0 C are carried out in a hydrogen stream, but is not required since it is activated very rapidly at the beginning and in the further course of the reaction.
- the hydrogenation of glycerol is carried out in the process according to the invention at hydrogen pressures of preferably 50-80 bar, and temperatures of preferably 200-220 ° C.
- the hydrogenation of glycerol of high purity of 99% by weight and higher is preferred. If crude glycerol from the transesterification of fats and oils is used in the process according to the invention, it should expediently be concentrated by distillation and freed from catalyst poisons such as the sulfuric acid often used as the transesterification catalyst.
- the inventive method has the advantage that a complete hydrogenation of the glycerol is achieved, wherein the desired reaction product 1, 2-propanediol is formed in high selectivity of up to 98 wt .-%.
- By-products are only monoethylene glycol and detectable in small amounts of ⁇ -propanol, which can be easily removed by distillation with the water of reaction. If required, the product mixture obtained can either be used directly for chemical applications or converted into pure 1,2-propanediol (> 99.5% by weight) by further purification by distillation.
- Example 1 Process for the preparation of 1, 2-propanediol by hydrogenolysis of glycerol on a CuO / ZnO catalyst
