Abstract
Provided are additives of formula I for use in hydrocarbonaceous compositions, such as petroleum or liquid fuels: (I) wherein R1, R2, R3, R4, and R5 are as defined herein. The additives improve the corrosion resistance of the compositions. The additives also enhance the antimicrobial efficacy of any added biocides contained in such compositions.
Claims1
A blend comprising:
- a hydrocarbonaceous composition;
- a corrosion inhibitory amount of an aminoalcohol that is:
- 1-aminocyclohexylmethanol or a mixture of 2-amino-2-methyl-1-octanol, 2-amino-2-ethyl-1-heptanol, and 2-amino-2-propyl-1-hexanol,
- or salt thereof;
- and
- a biocidally effective amount of a biocide that is a blend of 4-(2-nitrobutyl)-morpholine and 4,4′-(2-ethyl-2-nitrotrimethylene) dimorpholine.
