Furan Resin (F03) - Preparation Method

Open Data Verified Data
  1. furoic acid decarboxylation method 2 furan formic acid is heated to 200~250 degrees C (boiling point or so), that is, the decomposition of furan and carbon dioxide. During the reaction, the sublimed 2-furan formic acid was returned to the reactor, and the distilled furan was re-distilled to collect a fraction of 31-34 ° C. To obtain a relatively pure product with a yield of about 75%.
  2. furfural direct decarbonylation method the catalysts used in this reaction are aluminum silicate, metal oxides or hydroxides, and mixtures of alloys and metals, such as mixtures of chromium zinc and manganese, the reaction temperature is about 400 ℃, the yield is 90%, and the yield can reach 74% under the condition of large scale production.
  3. furfural oxidative decarbonylation method furfural was obtained by mixing furfural with water, passing air through molten metallic aluminum at 730 ° C. To oxidize and decarbonylate furfural. In addition, furfural and water vapor are passed together through quicklime and slaked lime at a temperature of 350 to 400 ° C. To remove the carbonyl group to produce furan.

physical properties furan is also known as "oxygen (heterocene)". Formula C4H4O. Molecular weight 68.07. Colorless liquid, with special odor, placed Brown, plus a small amount of water can delay discoloration. Solidification Point -86 ℃, boiling point 31.4 ℃, relative density 0.938, refractive index 1.4216. Insoluble in water, soluble in ethanol, ether., Volatile, easy to burn, stable to alkali, unstable to acid, and mineral acid contact polymerization. Its vapor is narcotic. Exposure to peroxides in air. Preparation Method: 2-furan carboxylic acid decarboxylation, or directly the furfural drop in the molten sodium hydroxide, potassium hydroxide mixture, can also be obtained by distillation of rosin. Purposes: for the synthesis of pyrrole, Tetrahydrofuran, thiophene, used as a solvent. In the drug there are a variety of furan derivatives such as furazolidone, nitrofurantoin and so on.
raw materials for organic synthesis furan is an important raw material for organic synthesis industry, which can be used to manufacture pyrrole, thiophene, tetrahydrofuran and benzofuran and other chemical raw materials, but also the manufacture of drugs anisodamine, atropine, sodium tosyl pyrrole acetate, furanthiamine and furan, etc. After the oxidation polymerization of furan, the conductive polymer can be obtained, and the conductivity is 18S/m (AsF5 is used as the oxidant) or 2.2 × 10-4S/m (NOSbF6 is used as the oxidant). Furan is unstable and prone to oxidation and polymerization. The catalytic hydrogenation of furan gives tetrahydrofuran.
Many derivatives of furan are drugs, such as furfural, furfuryl alcohol, furan carboxylic acid, furacilin, furan propylamine, furosemide, etc. In some monosaccharides such as fructose and ribose and their derivatives, there is a cyclic structure of hydrogenated furan.
hazard furan is highly volatile, with a boiling point of only 31 ℃, and is easily absorbed by the lungs or intestines through biofilm exposure in the air, cause Head Pain, dizziness, Nausea, Vomit, Respiratory Insufficiency and other symptoms, the liver, kidney and other damage, and even induce cancer.
uses mainly used for the production of large quantities of hot core box process core adhesive
furan used as raw materials and solvents for organic synthesis. Furan can be used to prepare pyrrole, thiophene, Tetrahydrofuran, etc., tetrahydrofuran is an important derivative of furan, there are many important uses. Furan is etherified and reduced to obtain 2, 5-dimethoxydihydrofuran, which is hydrolyzed to form 2-hydroxy-1, 4-butanedial and can be used in the production of synthetic anisodamine, when 2, 5-dimethoxytetrahydrofuran is obtained by reduction and then catalytic hydrogenation, butanedial is produced by hydrolysis, which is a raw material for the synthesis of another alkaloid atropine. Furan is also used in the production of the anti-inflammatory drug, sodium acetate, which consumes 4.75t of furan per ton of the drug.
production method 2-furancarboxylic acid is obtained by oxidation of furfural, and furan is obtained by decarboxylation. 2-furanic acid is heated to 200-205 °c (boiling point or so), I .e., it decomposes into furan and carbon dioxide. During the reaction, the sublimed 2-furanic acid was returned to the reactor, and the distilled furan was re-distilled to collect the 31-34 °c fraction to obtain a relatively pure product. The yield was about 75%. Direct decarbonylation from furfural is commercially available. The catalyst used in the reaction includes aluminum silicate, metal oxide or hydroxide, and alloys or mixtures of metals, such as a mixture of zinc chromite and manganese, at a reaction temperature of about 400 ° C. And a yield of 90%. The yield can reach 74% in large scale production.
