Sontsev, V. M. published the artcileConversion of propylene glycol-acetone mixture into 2,2,4-trimethyl-1,3-dioxolane over Dowex DR-2030 and ZrO2-SiO2 acid catalysts, Recommanded Product: 2,2,4-Trimethyl-1,3-dioxolane, the publication is Khimiya, Fizika ta Tekhnologiya Poverkhni (2014), 5(1), 42-46, database is CAplus.
The conversion of propylene glycol-acetone mixtures into cyclic ketal over sulforesin Dowex DR-2030 and acidic ZrO2-SiO2 catalysts under steady conditions at 40-100 °C has been studied. It has been shown that 2,2,4-trymethyl-1,3-dioxolane can be obtained with 99-94% yield at 40-50 °C. Conversion of propylene glycol increases from 65 to 75% when providing of the ketalization process with water removing.
Khimiya, Fizika ta Tekhnologiya Poverkhni published new progress about 1193-11-9. 1193-11-9 belongs to dioxole, auxiliary class Dioxolanes, name is 2,2,4-Trimethyl-1,3-dioxolane, and the molecular formula is C20H18BrN3, Recommanded Product: 2,2,4-Trimethyl-1,3-dioxolane.
