Abstract: A process for the storage and transport of chloroformic acid esters in tanks or pipelines which have a plastic inside surface, which comprises using a plastic having a total nitrogen content of from 0 to 100 ppm by weight, where this plastic forms from 20 to 100% of the inside surface, and the use of tanks or pipelines of this type for the storage and transport of chloroformic acid esters.

Abstract: The present invention provides process for the preparation of chlorocarbonyl chlorides of the formula I R1—CHCl—Y—COCl  (I), where R1 is for example hydrogen or C1- to C20-alkyl and Y is for example a saturated or mono- or polyolefinically unsaturated C2-C8-alkylene chain, by reacting lactones with a chlorinating agent in the presence of a urea compound.

Abstract: The present invention relates to a process for preparing alkyl, alkenyl and alkynyl chlorides from alcohols by reaction with a chlorinating agent in the presence of a catalyst, wherein the catalyst is a urea compound.

Abstract: A catalyst used for preparing thiochloroformates by reacting thiols with phosgene is a cyclic urea or cyclic thiourea which may be in the form of a salt obtainable by reaction with a hydrohalic acid or phosgene.

Abstract: Method and arrangement for dispensing a deicing liquid onto a traffic area through a stationary spraying arrangement. The method includes generating deicing liquid jets in the spraying arrangement, and discharging an amount of deicing liquid from each deicing liquid jet at a rate of less than approximately 1 l/min. The arrangement includes at least one deicing liquid pump, at least one deicing liquid conduit coupled to the at least one deicing liquid pump, and a plurality of spraying heads coupled to the at least one deicing liquid conduit. The spraying heads include at least one outlet opening having an inner diameter between approximately 0.1 mm and 1 mm.

Abstract: Neopentyl glycol hydroxypivalate (NGH) is isolated from a mixture containing NGH, lower- and higher-boiling products and inorganic salts and purified in a two-stage process, whereinin a first separation stage, the inorganic salts and part of the higher-boiling products are separated off in a wiped-film evaporator and a vapor stream consisting of NGH, lower- and higher-boiling products is discharged and fed to a heat exchanger and condensed therein,and, in a second separation stage, the resulting condensate is distilled in a rectification column from which NGH is taken off in a side stream and condensed. Further discharges of the rectification column containing lower-boiling products or higher-boiling products are separately taken off. The higher-boiling products which comprise residual NGH are partly or completely recycled to the lower region of the rectification column.

Abstract: A molybdenum metal powder having an outer shell coating of MoO.sub.2 is useful in flame spray or plasma spray processes and is prepared by partially oxidizing molybdenum powder in a carbon dioxide atmosphere at temperatures of up to 1200.degree. C.

Abstract: A process for the preparation of pourable choline chloride/silica powders by mixing silica with choline chloride and, where appropriate, drying this mixture, wherein spray-dried or fluidized bed-dried silica which has a particle size of from 30 to 250 .mu.m is mixed with an aqueous choline chloride solution which contains from 70 to 80% by weight, based on the solution, of choline chloride and is at from 40.degree. to 80.degree. C., thereafter from 0.05 to 0.4% by weight, based on the mixture, of magnesium stearate or calcium stearate is added and, if appropriate, the resulting mixture is dried.

Abstract: .alpha.-Vinyl-.alpha.-aminocarboxylic acids of the general formula: ##STR1## where * indicates a center of asymmetry and R is hydrogen, deuterium, lower alkyl, allyl, benzyl, or benzyl substituted 1 to 3 times by alkyl, alkoxy, fluorine or chlorine and produced enantioselectively from L-methionine by a multistep process.

Abstract: Neopentyl glycol hydroxypivalate is isolated from a reaction mixture obtained from a Tishchenko reaction of hydroxypivalaldehyde in the presence of calcium hydroxide, barium hydroxide or strontium hydroxide, by adding acid, removing the salts formed by adjusting the water content in the reaction mixture to 20-60% and extracting the salts at above 50.degree. C. and working up the residual mixture by distillation.

Abstract: Dioxane is produced by reaction of ethylene glycol or a polyethylene glycol using an acid catalyst. The reaction product containing dioxane, water and byproducts is subjected to extractive distillation with a high-boiling agent which is miscible with water.
