Abstract: A rubber track chain segment (1, 2) which can be connected via connecting devices (5) at the ends thereof to other rubber track chain segments (2) or to itself (1) to form a segmentable rubber track chain (3), wherein one or more tensile members (4) are introduced between the connecting devices (5) into the rubber track segment (1, 2) in order to increase the tensile load-bearing capability, wherein nipples are arranged at the ends of the tensile members (4), which nipples are set up to be received in an undercut of the connecting devices (5), the rubber band track segment (1, 2) has flexible regions (9) and less flexible regions (8) in an alternating manner, and the ends of the tensile members (4) are positioned in the less flexible regions (8) at the ends of the rubber band track segment (1, 2) so that the tensile members (4), from the exit (19) out of the nipples, run along as long a section (21) as possible through the less flexible regions (8) before they run through the adjoining flexible regions (9).

Abstract: A device for connecting two free ends of a rubber band track to one another or for connecting the ends of several band segments to one another. The device has two or more tubes and a pin rubber-mounted in the respective tube. The tubes are in each case inserted into the one end and into the other end of the rubber band track or of the band segments, and at least one connector, by way of which the pins are coupled together in a rotationally fixed manner. The rotational rigidity of the pins in relation to their respective tube, brought about by the rubber mounting, is adjusted in dependence on the flexural strength of the rubber band track or of the band segments in the region of the ends.

Abstract: The invention relates to a method for producing acid chlorides by converting carboxylic acids with carbon oxychlorides or thionyl chloride in the presence of a catalyst adduct of an N,N-disubstituted formamide of general formula (I) and carbon oxychloride or thionyl chloride. In the formula, R1 and R2, independently from one another, mean C1- to C4-alkyl or R1 and R2 together mean a C4- or C5-alkylene chain. According to the inventive method, hydrogen chloride is added during and/or after the conversion.

Abstract: Process for the purification of carbonyl chlorides which have been prepared by reacting carboxylic acids with phosgene or thionyl chloride in the presence of a catalyst adduct, in which the carbonyl chlorides are treated with a hydrohalide of carboxamides of the formula (I) in which R1 is hydrogen or C1- to C3-alkyl; R2 and R3 independently of one another are C1- to C4-alkyl, or R2 and R3 together are a C4- or C5-alkylene chain, and the carbonyl chloride purified in this way is isolated by separation off from the carboxamide hydrohalide phase.

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: In a process for finishing neopentyl glycol by cooling, crystallizing and comminuting a neopentyl glycol melt and subsequent packing of the resulting neopentyl glycol particles in storage or transport containers, the melt is cooled at the commencement of cooling for at least 1/10 minutes without use of a coolant or with use of a coolant having a temperature in the range from 50 to 120° C. and the product is packed at a temperature below 30° C.
