METHOD OF SYNTHESIS OF 2-METHYL-1,3-DIOXOLANE Russian patent published in 1995 - IPC

Abstract RU 2047609 C1

FIELD: organic chemistry. SUBSTANCE: product: 2-methyl-1,3-dioxolane, empirical formula is C₄H₇O₂, b. p. is 88.5 C, d24

⁰ 0.9861, n2D

⁰ 1.4120. Reagent 1: 1,4-dioxane. Process conditions: reagent is subjected for γ-irradiation at 140-160 C for 18-24 hr. Method ensures to simplify and decrease process cost by 3.6-fold. The use of solvent and catalyst is excluded. Product is used in organic synthesis as extractant of oil, fat and wax and as stabilizing agent of hydrogen halides. EFFECT: improved method of synthesis.
