摘要:
The present invention relates to an aqueous quick-setting bitumen-aggregate mix suitable for cold pavement of roads, parking places, sidewalks and the like. The bitumen-aggregate mix is manufactured by mixing a mineral aggregate, water, a de-emulsifier, containing hydraulic cement, and a cationic oil-in-water bitumen emulsion, containing, as an emulsifier, a salt of a tertiary diamine and a phosphoric acid. The diamine has the formula (I), where one or two of the groups R1, R2, R4 and R5 designate a hydrocarbon group of 6–22, preferably 8–20 carbon atoms, and the remaining R1, R2, R4 and R5 groups are an alkyl group with 1–4 carbon atoms, and/or a group —(A)2H, where A is an alkyleneoxy group with 2–3 carbon atoms, and s is a number from 1–4, R3 is an alkylene group with 2–4 carbon atoms and n is a number from 0–2.
摘要:
The present invention relates to a phospholipid composition comprising two or more phospholipids, the electric conductivity and pH of a 5 wt. % suspension of the phospholipid composition in deionized water being in the range of 130 to 220 .mu.S/cm and in the range of 6.5 to 9.5, respectively; a process for producing the same; and the use of the same.
摘要:
Emulsifiers are disclosed which comprise the reaction product of component (I) with component (II). Component (I) comprises the reaction product of certain carboxylic acids or anhydrides, or ester or amide derivatives thereof, with ammonia, at least one amine, at least one alkali and/or at least one alkaline-earth metal. Component (II) comprises certain phosphorus-containing acids; or metal salts of said phosphorus-containing acids, the metal being selected from the group consisting of magnesium, calcium, strontium, chromium, manganese, iron, molybdenum, cobalt, nickel, copper, silver, zinc, cadmium, aluminum, tin, lead, and mixtures of two or more thereof. These emulsifiers are useful in water-in-oil explosive emulsions.
摘要:
This invention concerns water soluble surfactants prepared by introducing solubilizing groups such as sulfates and polyoxyalkylenes into the dioxolane condensates of alkyl ketones with glycerol. These surfactants are particularly useful in detergent compositions.
摘要:
The present invention concerns the elimination of mineral oil, especially petroleum products by biological degradation. A composition is formed substantially by a phospho-amino-lipid mixed with a nontoxic and entirely biodegradable emulsifier, the phosphoamino-lipid being preferably lecithin. This composition may be used in liquid form for spraying floating oil-slicks and for cleaning tanks for mineral oil products and it may be brought into the form of a paste or powder by addition of mineral charges.
摘要:
Acyl-amino-propyl-dialkylammonium dialkyl phosphates as surface active agents and their application to textile materials, especially polyester and polyamide fibrous materials, as a finishing agent, for example, in combination with an aqueous emulsion of a textile lubricating agent.
摘要:
The present invention relates to synthetic, novel, preferably fatty phosphoric acid esters which, when neutralized with a neutralizing agent, is revealed as a new surface active agent. Formulations are presented which demonstrate a method for using the disclosed surface active agent to prepare stable oil-in-water, water-in-oil emulsions and various solutions of varying polarity and viscosity for use in a variety of dermatological applications, and/or wherever emulsions or solutions according to the present invention may be used.
摘要:
Surfactant containing one or more of lysophospholipid represented by general formula; ##STR1## [wherein R.sup.1 and R.sup.2 represent hydrogen atom or the acyl residue of fatty acid, but either one of R.sup.1 and R.sup.2 is hydrogen atom, the other being acyl group. X represents an organic group remaining after removing one hydrogen atom of an optional hydroxyl group of polyhydric alcohol therefrom] and the method for producing the same are described.
摘要:
A polyester article is treated with an aqueous emulsion of a halogenated phosphoric ester to retard its flammability. The aqueous emulsion is prepared by emulsifying a halogenated phosphoric ester with a nonionic surfactant derived from a phosphoric ester.
