Abstract: Device for differential thermal analysis employing pressure measurement which consists of heatable crucibles (3, 4) fitted with thermocouples (5, 6) for a specimen to be examined and for a comparison specimen. The temperature difference between the specimens can be measured by means of the thermocouples. For the purpose of pressure measurement, the specimen crucible (3) is sealed by a membrane (10) whose force is transmitted via a contact plunger (11) and a feeler rod (15) to a measuring transducer (12) whose output is connected to a display or recording device (16).

Abstract: A process is proposed for distilling ethylene oxide from a mixture containing ethylene oxide in a column at an absolute pressure of 2-10 bar and a temperature of 20-180 DEG C; pure ethylene oxide is removed at the top or through a side discharge in the column and distillation takes place in a column divided up internally into a number of successive zones with structured sheet metal packs or piles of fillers, one or more quenching systems located outside the column being allocated to said zones.

Abstract: Detergent components contain: (a) at least one dirt-removing amphiphilic polyester; (b) at least one antioxidant agent selected among the phenols, bisphenols and thiobisphenols substituted with sterically hindered groups, aromatic amines, preferably secondary aromatic amines and substituted p-phenylene diamines, phosphine, phosphite and phosphonite compounds, esters of 3,3'-thiodipropionic acid, reductones and metal ion disactivators; and (c) a carrier.
