Embodiment 1

[0034] Use biological oil (rapeseed oil) to produce biodiesel, and at the same time, the by-product is glycerol. This bioglycerol is in the presence of hydrogen at a temperature of 200 ° C to 500 ° C, using metal catalysts containing Ru-Ni metal coordination compounds , the reduction reaction is 2-20 hours, and the mixture product is obtained. After separation, bio-derived methanol (reaction yield 30%) is prepared, and the content of dimethyl ether is 0.5wt% after testing.

[0035] Bio-methanol passes continuously through the high-pressure reaction pipeline with a temperature of 300℃~600℃, in which the ZSM-5 zeolite catalyst containing Ni metal is loaded in the pipeline, and a mixture containing xylene is formed after the reaction. This mixture is recycled and separated by raw materials 1. Obtaining purity after rectification and refining is 95% p-xylene (reaction yield is 50%). Under the condition of 250℃ and 2.5Mpa pressure, in the presence of cobalt acetate, manganese aceta...

Abstract

The invention discloses a preparation method for aromatic polyester or aromatic nylon. During the preparation of the aromatic polyester or the aromatic nylon, a terephthalic acid unit is prepared and obtained by biological original methyl alcohol. According to the terephthalic acid unit in the components of the aromatic polyester or the aromatic nylon, the component of carbon is from biological materials instead of petroleum raw materials, the quantity of carbon dioxide (CO2) emitted during smelting of petroleum is greatly reduced, and the preparation method for the aromatic polyester or the aromatic nylon has a good environment-friendly effect, and is capable of being widely applied to the fields such as resin, fibers and film.

Description

technical field [0001] The invention relates to a preparation method of aromatic polyester or aromatic nylon. Background technique [0002] In recent years, with the continuous reduction of crude oil reserves and the recognition of the damage to the natural environment caused by the use of petrochemical resources, people have paid more and more attention to the use of biological resources in order to reduce the damage to the environment caused by industrial production. [0003] Organisms use solar energy to convert water and CO 2 Synthesized into organic compounds, these organic compounds are used as resources, and then decomposed into CO 2 And water, continue to be recycled. Biological resources are inexhaustible resources and energy. How to get rid of dependence on petrochemical resources and effectively use biological resources is the center of development and research by various countries and enterprises. [0004] Biological resources can be used in a wide range of f...
