Crude oil middle distillates with improved cold flow properties, containing small amounts of

Middle distillates of crude oil having improved cold flow properties

Novel reaction products of aminoalkylene polycarboxylic acids with secondary amines and their use as additives to middle distillates together with conventional ethylene copolymers as flow improvers and conductivity improves.

Novel reaction products of aminoalkylene polycarboxylic acids with

Pumpable free-flowing aqueous coal dispersions containing a special non-ionic dispersant which is a polyalkylene oxide bisphenol A derivative, and the use of the said dispersant in coal/water dispersions.

Aqueous coal dispersions

Aqueous, pumpable, free-flowing coal dispersions which may contain methanol and contain a special, oxyethylated, straight-chain, saturated fatty alcohol mixture as a nonionic dispersant, and the use of this dispersant in coal/water dispersions.

Petroleum demulsifiers which contain, as the active ingredients, oxyalkylated isoalkylphenol-formaldehyde resins and oxyalkylated polyalkylenepolyamines.

Demulsifiers for breaking crude-oil emulsions and their use

Salts of polymaleic acids, having molecular weights of from 200 to 1,500, with amines, of the formula ##STR1## where R.sup.1 and R.sup.2 are identical or different and each is hydrogen, C.sub.9 -C.sub.20 -alkyl or C.sub.9 -C.sub.20 -alkenyl and R.sup.3 is C.sub.9 -C.sub.20 -alkyl or C.sub.9 -C.sub.20 -alkenyl.

Ammonium salts of polymaleic acids, and their use as corrosion

Ethylene-alkyne copolymers and ethylene-alkyne-alkene terpolymers. The copolymers and terpolymers have a number-average molecular weight, determined by vapor phase osmometry, of from 500 to 500,000 and contain, as copolymerized units,

Ethylene-alkyne copolymers, their preparation and their use as additives

Polyhydroxy-polyalkylene-polyamine salts of maleic amide acids are useful metal corrosion inhibitors for use in water-in-oil emulsions.
