  • Process for the production of cyclopropanecarboxaldehyde
    Patent number: 5502257
    Abstract: Disclosed is a process for the preparation of cyclopropanecarboxaldehyde by the thermal isomerization of 2,3-dihydrofuran under superatmospheric pressure, e.g., at a temperature of about 300.degree. to 600.degree. C. and a pressure of about 3 to 345 bars absolute.
    Type: Grant
    Filed: February 21, 1995
    Date of Patent: March 26, 1996
    Assignee: Eastman Chemical Company
    Inventors: Shaowo Liang, Timothy W. Price, Timothy R. Nolen, Daniel B. Compton, David C. Attride
  • Gas phase process for the epoxidation of non-allylic olefins
    Patent number: 5362890
    Abstract: Disclosed herein is an improved gas phase process for the selective epoxidation of non-allylic olefins wherein the epoxidation is carried out in the presence of certain inert, paraffin hydrocarbons. Such hydrocarbons possess higher heat capacities as compared to other materials, e.g., nitrogen, argon, methane and helium, typically used as inert diluents in olefin epoxidations. The disclosed process is particularly useful for the continuous manufacture of 3,4-epoxy-1-butene from 1,3-butadiene.
