Abstract: A supply system for feeding a fluid to a vessel (1) is described, which is provided with a feedline (10), having a reservoir which is filled with the fluid and a compressed-gas store (14) which can be brought into communication with this reservoir (13), in which system the reservoir (13) and the compressed-gas store (14) are arranged in immediate proximity to one another, and wherein the reservoir (13) can, when required, be brought into communication with the feedline (10) via connection pieces (11, 12).

Abstract: The system to deliver a liquid into a container (1), has a feed line (10) from the container (1) to be linked to a liquid supply (13) fitted with a compressed gas bottle (14). The liquid supply (13) and the compressed gas bottle (14) are close together. The liquid supply (13) is connected (11,12) to the feed line (10) as required. A liquid pressure reduction unit (22) is between the compressed gas bottle (14) and the liquid supply (13). The liquid supply (13) and the compressed gas bottle (14) together form a mobile unit. The pressure in the liquid supply vessel does not exceed 10 bar and pref. is not over 6 bar. The connector (11,12) is automatically linked to the feed line when the gas bottle (14) is opened. The ratio of the effective diameter of the connector (11,12) to transfer the forces, to the hydraulic diameter, is at least 2:1.

Abstract: (Meth)acrylic esters are prepared by reacting (meth)acrylic acid with a C4-C12-alkanol in the presence of sulfuric acid or a mono-C4-C12-alkyl sulfate as catalyst, whereina) the reaction is carried out in an esterification unit which comprises a first reactor and at least one further reactor,b) a mixture of (meth)acrylic acid, C4-C12-alkanol and catalyst which contains not more than 5% by weight of water, based on the sum of the starting materials, is introduced into the first reactor,c) the esterification in the first reactor is conducted without removing ester, alkanol or water to a (meth)acrylic acid conversion of at least 40%, but only so far that the mixture remains a single phase, andd) the esterification is continued in at least one further reactor with the water formed being removed by distillation.
