Title: Jack Chosnek: Innovator in Chemical Processes

Introduction

Jack Chosnek is a notable inventor based in Corpus Christi, TX (US). He has made significant contributions to the field of chemical processes, holding a total of 2 patents. His work focuses on the purification of chemical compounds and the recovery of unreacted materials in industrial processes.

Latest Patents

One of Chosnek's latest patents is titled "Process for the purification of 4-acetoxystyrene." This invention relates to a method for purifying 4-acetoxystyrene from a crude product mixture that contains multiple contaminants. The process involves melt crystallization, where the mixture is cooled to a temperature between +8°C and -50°C. This allows for the crystallization of a portion of the mixture, followed by the removal of the remaining liquid. The crystallized portion is then slowly heated to eliminate impurities, achieving purities as high as 99.9% by weight.

Another significant patent is the "Ethylene recovery from ethyl acrylate process." In this invention, unreacted ethylene from a gaseous light ends stream is recovered by contacting it with a liquid sulfuric acid catalyst make-up stream. This reaction forms ethyl hydrogen sulfate and diethyl sulfate, which remain in solution and are utilized in the ethyl acrylate production process. This innovative approach ensures that sulfur dioxide in the vent-gas stream is not absorbed back into the sulfuric acid, optimizing the overall process.
