| 20100107478 | Oxazolidines derived from polyalkyl or polyalkenyl n-hydroxyalkyl succinimides, obtainment process and use - The present invention relates to oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides, the obtainment process thereof, and their use to prevent and control the formation of deposits in internal combustion engines, primarily in formulations of additives to be applied to hydrocarbon fuels. | 05-06-2010 |
| 20100140141 | Demulsifying and dehydrating formulations for heavy crude oils based on block copolymers bifunctionalized with amines - The present invention relates to demulsifying and dehydrating formulations of heavy crude oil based block copolymers amine bifunctionalized with low polydispersities. These formulations can contain solvents whose boiling point is in the range from 35 to 200° C., preferably: dichloromethane, chloroform, toluene, xylenes, turbosine, naphtha or mixtures thereof. | 06-10-2010 |
| 20110067295 | Formulations of random polymers for improving crude petroleum flow - The present invention is related to the use of formulations of new random copolymers and terpolymers, synthesized by a method of semi continuous emulsion polymerization, and that function as flow improvers, lowering the pour point and reducing the viscosity of Mexicans crude oils, which have gravities within the range of 9 to 30° API. | 03-24-2011 |
| 20110162558 | Formulations comprising an asphaltene-dispersing/inhibiting additive based on oxazolidines derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides - The present invention relates to formulations of asphaltenes' inhibitor-dispersant additives based on oxazolidine derived from polyalkyl or polyalkenyl N-hydroxyalkyl succinimides. Said formulations can contain inert organic solvents, preferably including: toluene, mixtures of xylene, o-xylene, p-xylene, kerosene, turbo-fuel; or inert hydrocarbon solvents having boiling points within the range of gasoline and diesel; or inert hydrocarbon or organic solvents having a boiling point within a range from 75 to 300° C. The ratio in weight of inert organic solvents to additive that prevents and controls the precipitation and deposition of asphaltenes ranges from 1:9 to 9:1, preferably from 1:3 to 3:1. | 07-07-2011 |
