Abstract
The invention discloses a demulsifier which comprises the following components in parts by weight: 10-15 parts of polypropylene oxide, 10-20 parts of sodium hydroxide, 8-13 parts of potash, 8-12 parts of sodium phosphate, 6-10 parts of water glass, 10-15 parts of water solubility sodium sulfonate soap, 15-20 parts of castor oil, 10-15 parts of naphtha, 1-3 parts of ammonium hydroxide and 10-15 parts of polyoxyethylene polyoxypropylene block polyether and 10-15 parts of a corrosion inhibitor. The demulsifier is simple in raw material, low in cost, environment-friendly, convenient to use and good in effect.
Description
Technical field
The invention belongs to chemical field, what be specifically related to is a kind of emulsion splitter.
Background technology
The emulsion splitter used in lubricating oil is also non-emulsifying agent usually, the reason causing lubrication oil content water-based difference or generation emulsification is many-sided, one is that lubricating oil viscosity is high, two is in industrial lubricant, be added with various additive, wherein major part is the tensio-active agent having emulsification function, three is oil product in use oxidized compounds creating the easy emulsifications such as carboxylic acid, and the resistance to emulsion of oil is degenerated.Deepen the refining depth of base oil, select suitable various additives to be no doubt a kind of problem that should first consider, but adding emulsifying agent is the main path improving lubricating oil resistance to emulsion.
After adding emulsion splitter; emulsion splitter is adsorbed on oil/water interfacial film, can change oil/water interfacial tension, eliminates the obstacle (namely eliminating the protective membrane outside liquid pearl) that disperse phase liquid pearl be combined with each other; make liquid pearl easily combine and realize phase in version, thus reach moisture object.When carrying out extracting and separating between organic phase and aqueous phase, often easily there is emulsification and make two-phase interface smudgy in two-phase mixtures system, is difficult to be separated.Often need use emulsion splitter for this reason, eliminate emulsion, organic phase and aqueous phase can be separated effectively.Because emulsion splitter uses in drug manufacture, so have requirements at the higher level to emulsion splitter, as breakdown of emulsion function is strong, consumption is few, impurity and pigment few, mouldiness is low, does not affect extraction yield and quality etc.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of emulsion splitter is provided, has good breakdown of emulsion system.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of emulsion splitter, following component is comprised: polyoxypropylene 10-15 part, sodium hydroxide 15-20 part, potash 8-13 part in components by weight percent, sodium phosphate 8-12 part, water glass 6-10 part, water-soluble sulfonic acids soda soap 10-15 part, Viscotrol C 15-20 part, petroleum naphtha 10-15 part, ammoniacal liquor 1-3 part, polyoxyethylene polyoxypropylene block polyether 10-15 part, inhibiter 10-15 part.
Preferably, following component is comprised: polyoxypropylene 11-13 part, sodium hydroxide 16-18 part, potash 9-11 part in components by weight percent, sodium phosphate 9-11 part, water glass 7-9 part, water-soluble sulfonic acids soda soap 12-14 part, Viscotrol C 16-18 part, petroleum naphtha 12-14 part, ammoniacal liquor 1.5-2 part, polyoxyethylene polyoxypropylene block polyether 11-13 part, inhibiter 11-13 part.
Preferably, described inhibiter is 2-sulfydryl thionaphthene or hydroxy ethylidene-diphosphate.
Preferably, the mass ratio of described ammoniacal liquor is 2%-5%.
The invention has the beneficial effects as follows:
Raw material of the present invention is simple, and cost is low, environmental protection, easy to use, has good breakdown of emulsion system, effective advantage.
