Abstract
Provides a process for the manufacture of mixed amides using C3～C30Natural or synthetic single or mixed fatty acid and naphthenic acid are mixed according to the mass ratio of 1-99: 99-1, and then react with organic amine for a certain time at normal pressure and a certain temperature to obtain series of mixed amides which can be used as a high-grade surfactant and the like to be applied to many fields.
Description
Technical field: the present invention relates to tensio-active agent and make field, especially a kind of manufacturing process of mixing acid amides.
Background technology: the acid amides of lipid acid is the tensio-active agent of a class excellent property, in fields such as daily-use chemical industry, industry, agriculturals many application is arranged.The acid amides of naphthenic acid also is the novel tensio-active agent of a class, and they are expected as dispersion agent, emulsifying agent, inhibitor, sterilant etc.The report of foreign study, manufacturing cycloalkanes acid amides is more at present, but mostly be the reaction of naphthenic acid and ammonia or organic amine and make the cycloalkanes acid amides, and method is complicated, need pressure or longer reaction times, do not see that having lipid acid to mix with naphthenic acid is being relatively easy to the synthetic report that mixes acid amides under the condition with amine again.Domestic about the cycloalkanes acid amides research and the report of production still rare (Tang Xudong. Speciality Petrochemicals .1994 (4): 75～78), particularly also not seeing has single or mixed fatty acid to mix with naphthenic acid to make the production that mixes acid amides and the report of widespread use.
Summary of the invention: the object of the present invention is to provide a kind of C of utilization
3～C
30Natural and (or) synthetic single or mixed fatty acid mixes with naphthenic acid, reacts with amine again, produces the manufacturing process of the new mixing acid amides of a class.They mix the hydrophilic-lipophilic balance (HLB value) and the amine value of regulating product by the kind of regulating lipid acid with ratio with naphthenic acid, improve their surfactivity, thus can be widely used in daily-use chemical industry, industrial rust-preventive agent, sterilant, beneficiation reagent, plastics, rubber accelerator, lubricating oil and oil fuel energy-conservation, wear-resistant, peace and quiet, disperse, fall dirty environment protection additive.
The technical scheme that realizes the foregoing invention purpose is as follows:
Get C
3～C
30Natural and (or) synthetic straight chain, side chain, replace, cyclisation saturated and (or) unsaturated fatty acids 1～99 (mass ratio, as follows) (comprise acidifying acid with naphthenic acid, thick acid, smart acid) 99～1 parts of mixing, again with ammonia, quadrol, a 1.2 propylene diamine, diethylenetriamine, Triethylenetetramine (TETA), polyethylene polyamine, Monoethanolamine MEA BASF, diethanolamine etc. reacted 0.5～8 hour under 90～300 ℃ of temperature of normal pressure, obtain the mixing acid amides of different HLB values (3～18) and different amine value (10～300mg KOH/g), they are optionally as clean-out system, rust-preventive agent, lubricating oil and fuel oil (comprise gasoline, synthetic gasoline, diesel oil, heavy oil, residual oil) wear-resistant, energy-conservation, dirty environment protection additive falls, the boiler foam preventer, sterilant, asphalt emulsifier, assistant for drilling petroleum well, beneficiation reagent, senior clock and watch, equipment antirust, slip additive, plastics, rubber accelerator etc.
The invention has the advantages that: utilize different chain length (C
3～C
30) the single and mixed fatty acid of different structure (straight chain, side chain, cyclisation) different saturation (saturated and unsaturated) different sources (natural and synthetic) mixes with naphthenic acid, adopt different kinds and proportioning to react with amine again, obtain the mixing acid amides of different HLB values (3～18) and amine value (10～300mg KOH/g), they have different amphipathic properties and surfactivity, can be selectively used for above-mentioned many fields according to different needs, thereby provide a series of new kinds for the function surface promoting agent.
