Description
Technical field
The present invention relates to a kind of novel method of the tetrahydrofurfuryl alcohol that by agriculture and forestry organic waste material is raw material acquisition being prepared to 1,5-PD by selectivity hydrogenolysis.Adopt specifically A-B/X or A/X loaded catalyst, compared with under mild conditions realize from the non-oil of 1,5-PD of agriculture and forestry organic waste material biomass, the renewable approach of preparing.
Background technology
Along with the worsening shortages of world's fossil resource, oil price constantly increases, and the renewable energy source chemical synthetic route that exploitation has high economic value added and high energy gamma source utilising efficiency is imperative.Biomass are unique reproducible carbon sources, and from unedible agricultural abandoned biomass, selectivity efficient conversion obtains energy chemical has become the focus of current research.Utilize the hyperoxic feature of biomass, it optionally can be converted into end has the dibasic alcohol of hydroxyl.Because this class dibasic alcohol has normal carbon chain structure, can be used as the monomer of polyester and urethane, have broad application prospects.1,5-PD is wherein a kind of.
1,5-PD is important chemical intermediate, is widely used in the products such as polyester, urethane, softening agent, coating, spices.At present, in prior art, the production method about 1,5-PD has:
1) cyclopentadiene photochemical catalytic oxidation at normal temperatures and pressures makes epoxypentenal, through 70 ~ 100 ℃, under the condition of about 6MPa, hydrogenation obtains 1,5-PD again, because problems such as the design of photooxidation reaction device, light source life and constant product quality, suitability for industrialized production is very limited.
2) Chinese patent CN1565728A reported with 1,5-Methyl glutarate be raw material, under CuZnAl catalyst effect, produce 1,5-PD.Its temperature of reaction is 150-350 ℃, and reaction pressure is 3-5MPa.This route need to be to reaction raw materials 1, and 5-pentanedioic acid is through esterification treatment, then carries out purifying, hydrogenation, and therefore reaction process is longer.
3) Chinese patent CN101225022A and Chinese patent CN101270032A have reported that respectively 5-glutaraldehyde hydrogenation is produced 1,5-PD with Ni based two-component loaded catalyst and loading type Ru catalyst 1.This class temperature of reaction is 60-120 ℃, and reaction pressure is 2.0-8.0MPa, and the security of the method is good, and by product is few, and shortcoming is that raw material resources are not abundant and price is high.
In sum, produce in the method for 1,5-PD, mainly take petrochemical complex product as raw material, petroleum resources are had to very strong dependency.So, prepare 1,5-PD from biomass agriculture and forestry organic waste material and there is certain economic value, also can alleviate the pressure to fossil energy demand.
Furfural is the product (common hemicellulose has: cereal shell, bagasse, corn cob, sunflower seed shell etc.) of crop by-product hydrolysis of hemicellulose.World's furfural annual production is larger, and annual approximately 280,000 tons, the wherein China of originating from over half.Due to the post-treatment technology to furfural of shortage, the furfural major part that China produces exports to foreign countries, and profit is lower, therefore has to be developed furfural effectively to be utilized to technology.Prepare 1,5-PD from furfural and not only can make full use of biomass resource, also the alternative production line take oil as raw material obtains the chemical of high value.Furfural 1,5-PD processed can be realized by following two kinds of methods:
1) furfural obtains furfuralcohol through preliminary hydrogenation, furfuralcohol direct hydrogenation under copper chromite catalysis obtains 1,5-PD, and this reaction is to 1,5-pentanediol selectivity is lower by approximately 30%, primary product is 1,2-pentanediol, therefore there is no industrial value (H.Adkins, R.Connor, J.Am.Chem.Soc.1931,53,1091);
2) prepare 1,5-PD by furfural complete hydrogenation product tetrahydrofurfuryl alcohol.In initial report, take tetrahydrofurfuryl alcohol as raw material, synthetic 1,5-PD need be through three steps: first tetrahydrofurfuryl alcohol is at Al
2o
3the lower dihydropyrane that generates of effect, dihydropyrane obtains 5-hydrogenation of hydroxypentylaldehyd through hydrolysis, and last 5-hydrogenation of hydroxypentylaldehyd generates 1,5-PD under copper chromite shortening.Although the method has overcome the low problem of selectivity of product, because needs carry out separating-purifying to each step reaction product, reactions steps complexity (L.E.Schniepp, H.H.Geller, J.Am.Chem.Soc.1946,68,1646).Nearest Japanese Tomishige seminar finds the Rh/SiO that utilizes Re, W or Mo to promote
2catalyzer is catalysis tetrahydrofurfuryl alcohol hydrogenolysis 1,5-PD processed (S.Koso, I.Furikado, A.Shimao, T.Miyazawa, K.Kunimori, K.Tomishige, Chem.Comm.2009,2035 effectively; S.Koso, H.Watanabe, K.Okumura, Y.Nakagawa, K.Tomishige, Appl.Catal.B-Environ., 2012,111 – 112:27), reaction is carried out in intermittent type tank reactor.But Rh is expensive due to precious metal, limit the application of this catalyzer in industry.Therefore, need a kind of have high reactivity, highly selective and moderate catalyzer, to realize the industrial application of preparing 1,5-PD from biomass.In the periodic table of elements, Ir and Rh are congenerss, and unit price lattice are lower than Rh.This seminar finds the Ir/SiO that Re, W or Mo promote recently
2catalyzer is catalysis tetrahydrofurfuryl alcohol hydrogenolysis 1,5-PD processed effectively, and reaction is carried out (Chinese Patent Application No.: 201110221524.X), the Ir/SiO promoting with Mo in all catalyzer in intermittent type tank reactor or fixed bed moving phase reaction device
