Corrosion inhibitors for fuels and lubricants

FIELD: chemistry.SUBSTANCE: invention relates to novel applications of corrosion inhibitors in fuels and lubricants. As corrosion inhibitors in diesel and carb fuel containing at least 0.1 part per million of alkali and/or alkali-earth metals and/or zinc, which are selected from a group consisting of sodium, zinc, magnesium and calcium, copolymers are used. Copolymers are obtained by reacting maleic anhydride and at least one α-olefin with 16–28 carbon atoms. Then, optionally, second reaction stage of partial or complete hydrolysis of anhydride functional groups contained in obtained at first reaction stage copolymer is carried out. Second reaction stage is carried out at least if the copolymer obtained at the first reaction stage does not contain free carboxylic acid functional groups. Copolymer has weight-average molecular weight M(determined by gel permeation chromatography with tetrahydrofuran and polystyrene as standard) 1500–4000 g/mol. Copolymers retain activity and do not precipitate in the presence of calcium.EFFECT: corrosion inhibitors have high compatibility with calcium ions and retain the action typical for corrosion inhibitors.5 cl, 1 dwg, 7 tbl, 3 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 689 799 C2 (51) МПК C10L 10/04 (2006.01) C08L 1/14 (2006.01) C10L 1/16 (2006.01) C10L 1/196 (2006.01) C08F 222/06 (2006.01) C08F 210/14 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C10L 1/146 (2019.02); C10L 1/1641 (2019.02); C08F 210/14 (2019.02); C08F 222/06 (2019.02); C10L 1/1963 (2019.02); C10L 1/1966 (2019.02) (21)(22) Заявка: 2016134922, 29.01.2015 29.01.2015 Дата регистрации: 29.05.2019 (73) Патентообладатель(и): БАСФ СЕ (DE) 29.01.2014 EP 14152991.7; 04.12.2014 EP PCT/EP2014/076622; 16.12.2014 EP 14198266.0 (56) Список документов, цитированных в отчете о поиске: EP 0307815 A1, 22.03.1989.

Drag reduction agent for hydrocarbon liquid

The present invention relates to improved drag reduction agents which are copolymers of an alpha olefin and a vinyl alkylenecarboxylic ester.

Bi- or Multi-Modal Particle Size Distribution To Improve Drag Reduction Polymer Dissolution

The frictional pressure drop, or drag, of hydrocarbon fluids flowing through pipelines of various lengths is preferentially lowered by dissolving therein polymeric drag reducer suspensions exhibiting bi- or multimodal particle size distributions. Drag reducers having larger particle sizes dissolve more slowly than drag reducers having smaller particle sizes, and vice versa. By using at least bi-modal particle size distributions, the drag reduction effect may be distributed more uniformly over the length of the pipeline where smaller sized particles dissolve sooner after injection (upstream in the pipeline), and larger sized particles dissolve later (further along the pipeline). Drag reducer suspensions with bi- or multimodal particle size distributions may be made by suspension polymerization.

Systems and methods of improving diesel fuel performance in cold climates

Embodiments of the present invention are directed toward systems and methods of providing a low-emissions diesel fuel for use in cold climates. Such fuels may be prepared by a Fischer-Tropsch process and include a pour point depressant. Furthermore, the fuel is used in conjunction with a heated fuel delivery system so that low cloud points are not necessary. Fuels prepared according to embodiments of the present invention may be produced in higher yields than otherwise possible because a higher paraffin wax content can be tolerated, thus obviating the need to remove or exclude the wax. These fuels are characterized by a sulfur content less than 1 ppm, a cetane number greater than 60, an aromatics content less than 1 wt %, and a difference between the cloud and pour points that is greater than about 5° C. The present fuel may be prepared by a Fischer-Tropsch synthesis from any number of carbon-containing sources such natural gas, coal, petroleum products, and combinations thereof.

Copolymer and use thereof for reducing crystallisation of paraffin crystals in fuels

FIELD: chemistry.SUBSTANCE: invention relates to a copolymer, a method for production thereof, use thereof, as well as to an oil fuel containing such a copolymer. Method of producing copolymer involves polymerising at least one maleic acid or derivatives thereof (A), at least one α-olefin, having at least 6 to inclusive 20 carbon atoms (B), at least one of C- up to C-alkyl ether of acrylic acid or methacrylic acid or a mixture of such alkyl esters (C) and optionally one or more additional copolymerisable monomers (D). Monomers (D) differ from monomers (A), (B) and (C). Polymerisation is carried out in solution at temperature from 50 to 250 °C in continuous mode. Further, reacting with at least one dialkylamine (E), wherein two alkyl radicals of at least one dialkylamine (E) are independently alkyl radicals having at least 17 to 30 carbon atoms. Dialkylamine used is di-n-octadecylamine, di-n-nonadecylamine or di-n-eicosylamine. Molar ratio of dialkylamine (E) and maleic acid or its derivative (A) in the copolymer is at least 1.2:1 and up to 2.0:1. Copolymer is used to reduce crystallisation of paraffin crystals in fuels, to improve flow properties at low temperature of oil fuels and to improve filtrability of oil fuels containing additives for improving fluidity at low temperatures. Oil fuel contains from 10 to 5,000 wt. parts per million of at least one said copolymer and optionally an additive. Additives are selected from a group comprising low-flow additives at low temperature, paraffin dispersants, additives for conductivity, additives for corrosion protection, lubricating additives, antioxidants, metal deactivators, antifoaming agents, demulsifiers, detergents, cetane number increasing additives, solvents, diluents, dyes and flavoring agents.EFFECT: invention reduces crystallisation of paraffin crystals in fuel, improves flow properties at low temperature of oil fuels, and improves filterability of oil fuels.11 cl, 6 tbl, 16 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) ...

Double-action additive, additive composition, and fuel

FIELD: petroleum processing and petrochemistry. SUBSTANCE: double-action additive, limiting and preventing precipitation of paraffins in middle distillates boiling away within 150-450 C, and also providing dispersing of paraffin crystals, consists of at least one modified copolymer with weight-average molecular weight 500 to 5000. Additive is prepared by copolymerization of first carboxylic acid with alkyl ester of second carboxylic acid, identical to the first or not, followed by amidation at 100 to 200 C of carboxylic groups in resulting copolymer with polyamide having general formula (RR′N-[-(CH 2 ) n -NH-]-H m ), in which n and m are within a range between 1 and 8 and R and R' are preferably alkyl groups.
