Description
Technical field
The invention belongs to the field of polymers, and in particular to a kind of agent of tri compound microwave abstracting and its application.
Background technology
Polyvinyl chloride (Polyvinyl chloride, abbreviation PVC) is polymerized by vinyl chloride under initiator effect
Thermoplastic resin, is one of five big general-purpose plastics.
Plasticizer is added in high molecular material the plasticity that can improve material, strengthens the flexibility of high molecular material, in day
Using extremely extensive, such as packaging bag, mat applying, wallpaper, toy in regular supplies.When some liquid in body or production and living
When being contacted with the high molecular material containing plasticizer, micro plasticizer can be extracted from high molecular material, if plasticizer contains
Measure excessive, Long Term Contact can then cause body necessarily to injure.
Phthalic acid ester (PAEs), also known as phthalate ester, are the general designations that phthalic acid forms ester.Have in plastics industry
It is widely used, is often added in plastics and is used as plasticizer.When being used as plastic plasticizer, generally referred to as adjacent benzene
The ester that dioctyl phthalate is formed with the alcohol containing 4-15 carbon.Since PAEs and polymer body only pass through hydrogen bond or Van der Waals force knot
Close, therefore can constantly discharge and be transferred in surrounding environment in use, become be widely present in air, water body,
Organic pollution in soil, so as to be prevalent in the environment of human lives.PAEs is typical environmental estrogens pollution
Thing, by plant absorption enter plant in, it may occur that biological concentration, Long Term Contact can influence human endocrine, cause deformity,
Canceration and mutagenesis, thus extensive concern both domestic and external was caused in recent years.
The phthalic acid ester that polyvinyl chloride raw material and product manufacturing most generally use at present has：Phthalic acid two
Methyl esters (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), diisobutyl phthalate
(DIBP), phthalic acid two (2- methoxyl groups) ethyl ester (DMEP), phthalic acid two (4- methyl -2- amyl groups) ester (BMPP),
Phthalic acid two (2- ethyoxyls) ethyl ester (DEEP), diamyl phthalate (DPP), dihexyl phthalate (DHXP),
Butyl benzyl phthalate (BBP), phthalic acid two (2- butoxy) ethyl ester (DBEP), dicyclohexyl phthalate
(DCHP), the own ester (DEHP) of phthalic acid two (2- ethyls), diphenyl phthalate (DPhP), phthalic acid two are just pungent
Ester (DNOP), dinonyl phthalate (DNP) etc..
The method of plasticizer mainly has soxhlet extraction, ultrasonic extraction and microwave abstracting etc. in extraction PVC at present, wherein micro-
Ripple extraction has the advantages that speed is fast, saves solvent, pollution is small, and application is more and more.But different types of sample carry out it is micro-
When ripple extracts, the factor such as species and polarity of extractant can influence extraction yield and instrument safety.Single solvent is used as extraction PVC
It is difficult to meet the conditions such as solubility, polarity, instrument applicability and high-recovery at the same time during middle plasticizer.
Therefore, a kind of new, with strong points microwave abstracting agent of necessary invention, to reach quick, accurately extract PVC
The purpose of middle plasticizer.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of tri compound microwave abstracting in view of the deficiencies of the prior art
Agent, the extractant it is with strong points, be exclusively used in plasticizer P AEs in extraction PVC, and the extractant wants temperature, pressure
Ask relatively low, it is not necessary to which maximum extraction can be achieved in very high microwave abstracting temperature and pressure, and extraction yield is high and reduces quick-fried tank etc.
Risk.
