    Abstract: 5,6-Dihydro-2H-thiopyran-3-carboxaldehydes of the formula where R denotes hydrogen or methyl, are prepared by a method in which acrolein or crotonaldehyde is reacted with hydrogen sulfide in a mineral oil whose boiling point is higher than those of the starting materials and of the end product, and the 5,6-dihydro-2H-thiopyran-3-carboxaldehyde is obtained by distillation. These aldehydes are important intermediates for the preparation of some crop protection agents.

    Abstract: PROCEDIMIENTO PARA LA OBTENCION DE CAPROLACTAMA POR CALENTAMIENTO DE ESTERES 6-AMINOCAPROICOS EN PRESENCIA DE UN MEDIO ORGANICO INERTE, LIQUIDO EN LAS CONDICIONES DE LA REACCION, CON UN PUNTO DE EBULLICION INFERIOR AL DE LA CAPROLACTAMA. EL PROCEDIMIENTO SE CARACTERIZA PORQUE SE EMPLEAN COMO MEDIO DE REACCION HIDROCARBUROS AROMATICOS CON UN PUNTO DE EBULLICION DE 80 A 240 GRADOS C, SE MANTIENE UNA TEMPERATURA ENTRE 100 Y 320 GRADOS C, Y SE OBTIENE CAPROLACTAMA A PARTIR DEL MEDIO DE REACCION.
