Process of preparing dispersions of alkaline earth metal compounds

Dispersions of calcium or barium compounds containing oxygen are prepared by reacting an oxide of the metal with methanol in the presence of a lubricating oil, an emulsifying agent and an acid or acid anhydride, e.g. carbon dioxide, sulphur dioxide or oxalic acid, the dispersed metal compounds being recovered in the oil. A hydrocarbon diluent aids recovery of the methanol. Emulsifying agents include oil-soluble phosphorus compounds derived from olefines and phosphorus sulphide, oil-soluble sulphonates and aromatic sulphonic acids, and oleic and linoleic acid salts or soaps.

A transparent colloidal dispersion of calcium carbonate in oil is obtained in a two-stage reaction in which, in the first stage, CO2 is passed into a suspension of finely-divided calcium oxide (derived by burning CaCO3 above 2000 DEG F.) in methanol of <1% by volume water content in an amount 5-50% of that required to convert CaO to CaCO3 and, in the second stage, the oil and an oil-soluble dispersant are added and further CO2 is passed in to complete absorption, the dispersion then being distilled to remove methanol, treated with water and dehydrated. A thinner such as a "naphtha," particularly Stoddard solvent, kerosene, or preferably varnish maker's and painter's naphtha or alternatively an aromatic solvent such as benzene, toluene or xylene or a chlorinated solvent such as carbon tetrachloride or trichlorethylene may be included in the oil dispersion.

Method of producing low-ash alkylsalicylate detergent-dispersing oil additive

FIELD: oil and gas industry. SUBSTANCE: invention relates to oil refining. Method involves obtaining low-ash alkylsalicylate detergent-dispersing magnesium additive by neutralisation of alkyl(C 8-18 )salicylic acid with a calculated amount of magnesium oxide MgO in presence of water, straight-run gasoline with boiling intervals 80–180 °C and oil M-6 at temperature 70–80 °C for 1–2 hours. Magnesium oxide used is its active form, characterised by iodine number not less than 75 mg-eq I 2 /100 g MgO. Reaction mixture is fed into a carbonator reactor, where after adding a promoter – methanol and gasoline-solvent at 60 °C while stirring, carbonation of mixture fed into reactor with carbon dioxide occurs (molar ratio of MgO:CO 2 =1:1). After carbonation reaction mixture is held for 30–120 minutes at temperature 45–65 °C, after which temperature in reactor is gradually increased to 90 °C and from reaction mass at low pressure promoter and water are distilled off. Further, reaction mass is purified from unreacted MgO by centrifuging at speed. Gasoline-solvent is removed by distillation in a vacuum. EFFECT: method of producing detergent-dispersing additive is characterised by simplicity, manufacturability and low waste yield, and obtained product has high alkaline number with low ash content and is characterised by a system of improved antiwear properties of oil-base. 1 cl, 1 tbl, 1 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 611 431 C2 (51) МПК C10M 159/20 (2006.01) C10M 159/22 (2006.01) C10M 129/54 (2006.01) C10N 30/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ФОРМУЛА (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ 2015123987, 19.06.2015 (24) Дата начала отсчета срока действия патента: 19.06.2015 Дата регистрации: Приоритет(ы): (22) Дата подачи заявки: 19.06.2015 (43) Дата публикации заявки: 10.01.2017 Бюл. № 1 Адрес для переписки: 446200, Самарская обл., г.
