Abstract: An improved device for the distribution of liquids in a vertical heat-exchange apparatus which has reeds mounted on the top ends of vertical tubes to spread a liquid in film form over the internal surface of each tube of the tube bundle. The reeds of the invention are closed at their tops instead of being open as was common in conventional practice, and the reeds have an array of circumferential perforations near their closed tops for venting off gases and vapors which evolve from said liquid, while tangential perforations extend through the peripheral surface of the reeds in intermediate sections thereof. The pressure drop of gases and vapors can be adjusted within a wide range and corrosion in the top portion of the tubes is very efficiently prevented.

Abstract: A process for preparing tertiary alkyl ethers from isoolefins and aliphatic alcohols in the presence of a catalyst in the form of sulphonated styrene-divinylbenzene resins, characterized in that both the reaction leading to the formation of the tert-alkyl ether and the separation of the tert-alkyl ether from the hydrocarbons and compounds which accompany it take place in a single plate fractionating apparatus, in which some of the plates are provided with beds of catalyst in the form of spherules suitable for preparing said tert-alkyl ether, the ether obtained being withdrawn as a substantially pure bottom product.

Abstract: Rust-inhibiting compounds, especially for aqueous systems such as tool-lubricating emulsions for machine tools and which consist of amine salts of a number of monoaminoalkylene dicarboxylic acids are disclosed. These rust-inhibitors are used in combination with water and an alkanolamine. Examples and test results are given.
