Publication number: 20240067596Abstract: The present invention relates to a continuous process for obtaining 2-ethylhexyl acrylate (2-EHA) from a mixture (1) that is liquid under an absolute pressure in the range from 0.5 to 100 bar and has a temperature in the range from 0 to 300° C., comprising 2-EHA, at least one high boiler, at least one homogeneous catalyst, and at least one low boiler, wherein the mixture (1) is depressurized by a pressure-maintenance device (3) to an absolute pressure level in the range from 0.1 to 10 bar, wherein the resulting two-phase gas/liquid mixture (16) is continuously supplied to a helical-tube evaporator (4) in which, at a temperature in the range from 50 to 300° C., the 2-EHA content of the liquid phase of the two-phase gas/liquid mixture is reduced by partial evaporation, this being accompanied by a parallel increase in the 2-EHA content of the gas phase of the two-phase gas/liquid mixture, and the two phases are discharged in the form of a resulting two-phase gas/liquid output stream (17).Type: ApplicationFiled: January 24, 2022Publication date: February 29, 2024Inventors: Ortmund LANG, Claus HECHLER, Cornelis DE RUITER, Marvin KRAMP, Dominik HERBRECHT

Patent number: 11655228Abstract: The present invention relates to a process for preparing dioxolane by reacting ethylene glycol with an aqueous solution of formaldehyde in the presence of an acid catalyst. The raw product comprising water, dioxolane and methanol is fed to a phase separation unit (20) wherein an organic extracting agent is present. An organic fraction stream from the phase separation unit is transferred to an upper part of a purification column (30) from which dioxolane is withdrawn as a bottom product while the distillate stream of the purification column is recycled to the phase separation unit.Type: GrantFiled: May 8, 2019Date of Patent: May 23, 2023Assignees: BASF SE, Kolon Plastics Inc.Inventors: Thomas Heitz, Marvin Kramp, Manfred Heilig, HyunSoo Chang, JongMoon Kim, In Gi Cho
