Latest Patents

Among his latest innovations is a process for the continuous preparation of 3-(methylthio)propanal. This process involves a liquid reaction medium that is contacted with a gaseous acrolein feed stream in a gas/liquid contact zone. The reaction medium contains 3-(methylthio)propanal, methyl mercaptan, and a catalyst for the reaction between methyl mercaptan and acrolein. The gaseous acrolein feed stream comprises acrolein vapor and non-condensable gas. Acrolein is transferred from the feed stream to the reaction medium, where it reacts with methyl mercaptan to produce a liquid reaction product containing 3-(methylthio)propanal. The non-condensable gas is then separated from the liquid reaction product, which is divided into a product fraction and a circulating fraction. The circulating fraction is recycled back to the gas/liquid contact zone, enhancing the efficiency of the process.
