Abstract
The invention relates to the preparation and development of a method for a process for preparing a Poly Methylamine surfactant. The process consists of a mixture of methanol and ethanolamine in a molar ratio ranging from 1.0-0.6 to 3.0-0.4 at a temperature of 45-50° C., resulting in a non-hazardous substance, without toxic effects for human health, at the same time having high-quality cleaning, high- and very low temperature resistance, with surface active agent (surfactant) properties. Used as a fuel additive, reduces harmful exhaust gas emissions to the atmosphere, raises the octane number in gasoline, prevents the formation of ice crystals in diesel fuel.
Claims5
1) Multifunctional, ecological Poly Methylamine surfactant, with surface active (surfactant) properties, characterized in that:
- a) the methanol interaction with Mono Ethanolamine, in a molar ratio of 1.0:0.6, produces mono ethanolamine methylate—as intermediate product, subsequent condensation with Ethoxylate Nonylphenol (Rokanol NL8) as a sealant as a non-ionic surfactant gives a surface active Poly Methylamine agent.
- b) By the interaction of methanol with Diethanolamine in a molar ratio of 2.0:0.5 is obtained Methylate of Diethanolamine—as an intermediate product, subsequent condensation with Ethoxylate Nonylphenol (Rokanol NL8) as sealant as a non-ionic surfactant, Poly Methylamine surface active agent is obtained.
- c) By the interaction of Methanol with Triethanolamine in a molar ratio of 3.0:0.4, triethanolamine methylate- as intermediate product is obtained, subsequent condensation with Ethoxylated Nonylphenol (Rokanol NL8) as a sealant as a non-ionic surfactant, a Poly Methylamine surface active agent is obtained.
2) Poly Methylamine surfactant used as a fuel additive, characterized by reducing exhaust emissions to the atmosphere, raising the octane number in gasoline, preventing the formation of ice crystals in diesel and being anticorrosive.
3) Process for the preparation of a Poly Methylamine surface active agent (surfactant) characterized in that it takes place in the first step by reacting methanol and an ethanolamine at a molar ratio of 1.0-0.6 to 3.0-0.4 at a temperature of 45-50° C. to 55-60° C. with stirring for 2.5 hours:
- xCH3OH+NHy—(CH2—CH2—OH)x→{[NHy—(CH2—CH2—OH2)x]+[(CH3O)x]−}
- where
- x=1-3
- y=0-2
- x+y=3
- followed by a second step in which the reaction between the product obtained in the first step and the Ethoxylated Nonylphenol having the degree of Ethoxylation 30 at 55-60° C. takes place for 1.5 hours.
- Where:
- x=1-3
- y=0-2
- x+y=3
- z=6 -9
