Abstract
Improving the flowability of mineral oils and mineral oil distillates using alkylphenol-aldehyde resins The invention relates to a process for improving the flowability of paraffin-containing mineral oils and mineral oil distillates by adding flow improvers based on ethylene/vinyl ester co- and terpolymers, alkylphenol-aldehyde resins and, if appropriate, other paraffin dispersants, mixtures of these different flow improvers and mineral oils and mineral oil distillates which comprise these flow improvers.
Claims34
A process for improving the flowability of paraffin-containing mineral oils and mineral oil distillates, which comprises adding to the paraffin-containing mineral oil or mineral oil distillate
- A) at least one ethylene/vinyl ester co-or terpolymer, and
- B) at least one alkylphenol-aldehyde resin consisting of a condensate of up to 50% phenol and identical or different alkyl phenols with an aldehyde, where the resin or the resins contain at most 10 mol % of alkylphenol which contain more than one alkyl group, and optionally
- C) at least one paraffin dispersing compound different than B).
A mixture of
- B) 10-90% by weight of at least one alkylphenol-aldehyde resin consisting of a condensate of up to 50% phenol and identical or different alkylphenols and an aldehyde and
- C) 90-10% by weight of at least one paraffin dispersing compound different from B
- The total of the additives B and C always being 100% by weight.
A mixture of
- A) 5-90% by weight of at least one ethylene/vinyl ester co- or terpolymer and
- B) 5-90% by weight of at least one alkylphenol-aldehyde resin consisting of a condensate of up to 50% phenol and identical or different alkylphenols and an aldehyde and optionally
- C) 5-10% by weight of at least one paraffin dispersing compound different from B
- the total of the additives A, B and C always being 100% by weight.
A mineral oil or mineral oil distillate comprising
- A) at least one ethylene/vinyl ester co- or terpolymer and
- B) at least one alkylphenol-aldehyde resin consisting of a condensate of up to 50% phenol and identical or different alkylphenols and an aldehyde and, optionally
- C) at least one paraffin dispersing compound different from B.
An additive mixture for paraffin dispersion in paraffin-containing mineral oils and mineral oil distillates comprising at least one paraffin dispersing compound and at least one aliphatic or aromatic liquid hydrocarbon as solvent, wherein at least one alkylphenol-aldehyde resin is added as solubilizer.
A process for preparing solutions of paraffin dispersants in aliphatic or aromatic liquid hydrocarbons, which comprises adding to the mixture of these substances an alkylphenol-aldehyde resin.
