The preparation method of isopentene is characterized in that
Antibiotic Precursor Synthesis Isopentene is used as a raw material, firstly Isopentene in Antibiotic Precurs or Synthesisis introduced into a tube-in-tube fixed bed reactor, activated alumina is used as a catalyst, and Isopentene in Antibiotic Precursor Synthesis is subjected to a dehydration reaction at a temperature range of 350° C. to 400° C. and normal pressure to obtain a mixed gas whose main component is 3-methyl-1-butene; then the mixed gas is subjected to a further isomerization reaction in another tube-in-tube fixed bed reactor at a reaction temperature of 500° C. to 520° C. to obtain a desired product whose main components are 2-methyl-2-butene and 2-methyl-1-butene.
Purpose
Antibiotic Precursor Synthesis Isopentene is used to synthesize a variety of drug intermediates, such as β-ethylaminoacetic acid, propionate amine, phenobarbital, etc., these intermediates can be further processed into various drugs.
Anticancer drugs, antibiotics and antiviral drugs: Isopentene in Antibiotic Precursor Synthes can also be used to prepare pharmaceutical intermediates such as caronic acid anhydride, and then produce anticancer drugs, antibiotics and antiviral drugs.
Isopentene in Antibiotic Precursor Synthes is used in the synthesis of many chemicals and chemical intermediates and has many applications, including: flavors, fragrances, pesticides, growth regulators, pharmaceuticals, health products, catalysts, peroxides, phenolic resins, hot melt adhesives, antioxidants and UV stabilizers.
