摘要:
Compositions are described which comprise oxyalkylated polyglycerol esters, one or more organic solvents and water. The compositions are exceptionally suitable for the thickening of surfactant-containing systems.
摘要:
Disclosed is a coolant collector (1) comprising a filter/dryer unit (10) and an elongate, vertically oriented interior space which is subdivided into an upper area (38) and a lower area (39) by means of the filter/dryer unit (10). A flowing coolant is delivered to the filter/dryer unit (10) via a pipe (7). The outlet windows of the filter/dryer unit (10) are located on the outer circumference thereof which delimits a relatively narrow gap along with the wall (3) of the receptacle (2) of the coolant collector (1). Liquid components drip downwards and accumulate below the filter/dryer unit while gaseous components accumulate primarily above the filter/dryer unit (10).
摘要:
An internal refrigerating machine heat exchanger (11) which increases the efficiency of the refrigerating machine (10) comprises a pipe having an internally arranged low-pressure channel and having a substantially larger cross-section than all of the high-pressure channels provided on the outside of the pipe. In addition, the inside width of the low-pressure channel is at least as large as the inside width of the connecting lines (17, 21). Preferably, the wall of the low-pressure channel is smooth.
摘要:
The invention relates to cosmetic and pharmaceutical compositions containing a fragrance and at least one emulsifier comprising a) at least one alkyl chain and/or alkenyl chain having at least 28 carbon atoms obtainable by polymerization of (C2-C5)-alkenes and which is linked with b) at least one carboxylic acid, carboxylic acid derivative, carboxylic anhydride, carboxylic anhydride derivative, ester and/or amide group. Particularly preferred emulsifiers are alkenylsuccinic anhydrides according to formula (1) and derivatives thereof, in which n is equal to or greater than 4.
摘要:
A terpolymer comprising monomer units derived from an olefin having more than 40 carbon atoms, maleic anhydride, and an alkylallyl polyglycol ether of the formula R—(OCH2CH2)nO—CH2—CH═CH2 where n=3-20 and R=C1-C4-alkyl.

摘要:
The invention provides an explosive composition consisting of A) an oxygen-donating constituent, which forms a disperse phase, B) an organic constituent, which forms a dispersion phase, and C) at least one emulsifier, wherein the emulsifier includes a copolymer comprising, in random or regular order, structural units derived from maleic anhydride and from one or more olefins having more than 40 carbon atoms, where the structural units derived from maleic anhydride have been modified by reaction with alcohols, aminoalcohols, ammonia or amines.
摘要:
The invention relates to an additive for inhibiting gas hydrate formation, containing a) from 5 to 90% by weight of 2-isobutoxyethanol, b) from 5 to 60% by weight of a copolymer which has structural units which are derived from maleic acid, maleic anhydride or derivatives of maleic acid or of maleic anhydride, and c) at least 10% by weight of water or a monohydric or polyhydric alcohol, except the 2-isobutoxyethanol, or mixtures of the stated substances, based on the total weight of the additive, the sum of the contents of compounds a) and b) being from 10 to 90% by weight, and a process for inhibiting gas hydrate formation using 2-isobutoxyethanol.
