Description
Technical field
The present invention relates to amphoteric surfactant technical field, more particularly to a kind of fluorine-containing carboxylic acid type beet alkali ampholytic from
Sub- surfactant and preparation method.
Background technology
Fluorine-containing hydrocarbon-based surfactant with its unique " three high ", " two hate " performance, i.e., surface-active, heat-resistant stability and
Chemical stability is high.With the increasingly increase of domestic and international market, fluorine-containing surfactant excellent performance is with high content of technology, attached
It is value added big, cause the great interest of lot of domestic and foreign researcher.Its fluorine-containing alkyl have water and oil repellant [new chemical materialses, 2004,
32(8)：46], it is widely used in oil exploitation, coal is metallurgical, mechanical industry, medicine, agricultural etc. field [household chemicals,
2011,41(4)：40-43].The excellent application performance of fluorine-containing surfactant, the accreditation in market, demand day have gradually been obtained
Benefit increase, although the added value of fluorine-containing surfactant is high, technology content is also high.Nearly ten years, novel fluorine surface-active
Agent molecule structure continues to bring out, and has the novel fluorines such as double carbon fluorine chains, the hydrocarbon heteroduplex of carbon fluorine, double hydrophilic chains, more hydrophilic chains
Surfactant is reported in succession.Although the development of fluorine-containing surfactant has obtained significant progress, but still suffers from quantity
Less, the state of single varieties, as perfluor anion surface active PFOA products are difficult to degrade, its application is restricted.
Betaines amphoteric surfactant is relatively early commercialized surfactant, due to internal salt structure be present in molecule
Characteristic makes it not only have fabulous salt-resistance, and good surface-active can be also kept in the range of wider pH value, still wide so far
It is general to be applied in the industries such as daily use chemicals, printing and dyeing.But in some special application fields, as fabric finishing agent, levelling agent, extinguishing chemical,
Demulsifier and collection finish etc. still feel deficiency；And fluorine-containing aliphatic alkyl betaine type amphoteric surfac-tant is in extremely low critical glue
Beam concentration also has excellent surface-active, is much better than amphoteric surfactant containing alkyl betaine-type.
Usually contain C3-C12Fluorohydrocarbon based surfactants all there is excellent surface-active, but perfluorochemical is wide
It is general to apply a series of environmental problems also brought, as perfluorooctanoic acid salt (PFOA) has the basic of persistent environmental organic pollution
Feature.2006, main fluorine material manufacturer of 8 worlds including Du Pont, 3M, great Jin, A Kema etc. signed PFOA
Emission reduction agreement, promise stop using PFOA stage by stage.PFOA will be all prohibitted the use of in all products in 2015 and can be derived
PFOA compound.Meanwhile existing fluorine-containing surfactant poor-performing, in some extreme environment, as in high salt
In environment, surface tension shows poor, influences using effect, reduces application.
