Abstract: The invention concerns a process for the esterification of (meth)acrylic acid with an alkanol, oxyesters formed as a by-product of esterification being cleaved in turn in an acid-catalysed manner by the addition of monomeric and/or oligomeric (meth)acrylic acid and water.

Abstract: An apparatus for introducing a fluid into a container includes a supply leading into the interior of the container, closed by a bursting disk and connected to a supply line for the fluid. In order to increase the operational safety and to avoid clogging of the bursting disk, the supply is in the form of a telescopic tube which can be extended by the pressure of the fluid into the interior of the container and is mounted above the highest level in the container.

Abstract: A process for the esterification of (meth)acrylic acid with an alkanol in presence of a catalyst, in which unreacted starting cpds. and the required ester are sepd. by distn. and a bottom prod. contg. an oxy-ester is obtd. The process involves taking off the bottom prod., sepn. of the oxy-ester by distn. and cleavage of the distillate in presence of acid (I) at elevated temp.

Abstract: En un procedimiento para esterificar ácido (met)acrílico con un alcanol en presencia de un catalizador de esterificacion, en donde los compuestos iniciales no convertidos y el (met)acrilato a formar se separan mediante destilacion y se forma un producto de fondo que contiene oxiésteres, el producto de fondo se separa primero, los oxiésteres contenidos ahí se separan después mediante destilacion y el destilado resultante se disocian en presencia de ácidos a temperaturas elevadas. El procedimiento puede efectuarse en presencia de oxígeno molecular. El destilado se disocia a temperaturas ubicadas entre 170 y 250 degree C, de preferencia entre 180 a 230 degree C.
