Abstract
A kind of application the invention discloses benzophenone derivates and its in prepared by resistance to irradiation makrolon material, its structural formula is as follows, and G is C1 C10 alkyl or methoxyl group in formula.Benzophenone derivates of the present invention have the function that good stabilized radical, free radical stabilizer can be used as, the derivative is added in makrolon as free radical stabilizer can be made radiotolerant makrolon, the preparation technology of the resistance to irradiation makrolon is simple, easily operated implementation, xanthochromia, atomization can be mitigated under gamma Rays or high energy electron beams, more conducively applied.
Description
Technical field
The present invention relates to a kind of benzophenone derivates, the compound can be as the free radical stabilization of makrolon material
Agent, its xanthochromia, atomization during gamma-radiation or high-energy electron beam irradiation is prevented, the invention further relates to contain the hexichol first
The makrolon material of ketone derivatives, it has good radiation hardness, the performance of anti-xanthochromia.
Background technology
Makrolon（PC）As thermoplastic, due to its excellent performance, for example, the transparency, high tenacity, impact resistance
Property strong, heat resistance and processing dimension stability etc., the green grass or young crops of people has more and more been obtained in engineering plastics field in recent years
Look at.Polycarbonate products are not molded only or compression molding part, also film, sheet material etc..Due to excellent optics
Performance, makrolon have miscellaneous purposes in the field such as medicine equipment and consumptive material, for example, syringe, operating theater instruments, quiet
Arteries and veins transfusion, anesthesia tank, intravenous connectors and accessory, centrifugal blood bowl, blood oxygenators, blood purification, surgical instruments and
Operating room facilities etc..Makrolon has excellent mechanical strength and toughness, heat-resisting quantity and blood compatibility, in existing rank
In the high-tech Medical Devices and packaging market of section, makrolon is that one kind is especially suitable for, and the macromolecule material being accepted
Material.
, it is necessary to be sterilized when makrolon is used for medicine equipment.The ethylene oxide sterilizing used at present, due to epoxy second
Alkane itself is poisonous, residue problem be present and causes environmental pollution；And disinfection with high pressure steam can then cause makrolon in high temperature height
Aging under the conditions of wet.Irradiation sterilization is one using the microorganism caused by electromagnetic radiation on the most of materials of electromagnetic wave kill
The effective method of kind, this radiation is mostly using gamma-radiation radiation or high-power electron beam.When makrolon is exposed to sufficient dosage
Irradiation in when, resin can xanthochromia and atomization.Xanthochromia can change the color and mechanical property of makrolon material, thus can drop
The effect of low product in actual applications.Atomization can influence the transparency of makrolon, influence vision.So need to find one kind
Xanthochromia and the additive of atomization can be suppressed during makrolon irradiation sterilization.
The radiation-resistant property common practices for improving makrolon material is to add a small amount of stabilizer.For example, United States Patent (USP)
4624972 disclose a kind of esters prepared by aromatic multi-carboxy acid and alkyl substitution polyol reaction to improve makrolon material
The performance of resistance to y-radiation of material, in addition, United States Patent (USP) 4873271 discloses a kind of esters of polyalkylene oxide as stabilizer
The purpose is equally reached.Foreign countries also have some patents, such as United States Patent (USP) 5187211,4804692,4963598,
4874802nd, 5214078 be all to improve the radiation-resistant property of makrolon material by adding stabilizer.
Applicant once applied for a kind of resistance to irradiation makrolon material and its preparation method and application, the patent in 2012
In it is resistance to irradiation makrolon material be made up of makrolon, free radical stabilizer, epoxide diluent, plasticizer etc., wherein freely
Based stabilizer is 2,5 di tert butyl hydroquinone, hydroquinones dibenzyl ether, dibenzyl ketone.The patent is poly- except that can improve
Outside the yellowing problems of carbonic ester, also its mechanical property, chemical property and biological property are changed by other additives.

The present invention xanthochromia, fogging problem under gamma-radiation radiation or high-power electron beam for makrolon material, there is provided
A kind of new compound --- benzophenone derivates, the compound can be as the free radical stabilizer of makrolon, Neng Goufang
Only makrolon xanthochromia, atomization during gamma-radiation or high-energy electron beam irradiation are penetrated.
Present invention also offers application of the benzophenone derivates as makrolon free radical stabilizer, and comprising
A kind of makrolon of resistance to irradiation of benzophenone derivates.Present invention also offers the simple preparation side of the resistance to irradiation makrolon
Method.
Concrete technical scheme of the present invention is as follows：
A kind of benzophenone derivates, it is characterized in that：Its structural formula is as follows, and G is C1-C10 alkyl or methoxyl group in formula；
In above-mentioned benzophenone derivates, the G be methyl, ethyl, propyl group, butyl, amyl group, hexyl, heptyl, octyl group,
Nonyl, decyl, methoxyl group, preferably methyl, ethyl, propyl group, butyl, methoxyl group, most preferably methyl.
Benzophenone derivates of the present invention are reacted using friedel-craft（Friedel-Crafts）Prepare, reaction equation is as follows：
Preparation method is：In the three-necked flask equipped with thermometer and reflux condensing tube, with carbon disulfide（300ml）To be molten
Agent, the benzene of 1.0-1.5 moles of substitution is added to the chlorobenzoyl chloride and 1.0-2.0 moles of aluminum trichloride (anhydrous) of 1.0 moles of substitutions（Urge
Agent）In the mixture of formation, 40-50 DEG C is heated to, keeps boiling, back flow reaction 2-4h.Cooling, add 400ml frozen water and mix
Compound and about 120ml concentrated hydrochloric acid hydrolysis residues.Organic phase is separated, washing, dries, remove organic solvent etc., finally obtaining white
Color crystalline product.
Benzophenone derivates of the present invention can be used as free radical stabilizer, especially can be as makrolon material
Free radical stabilizer.Contain 6 substituents in benzophenone derivates of the present invention, it adds poly- carbonic acid as free radical stabilizer
Makrolon xanthochromia, atomization can be prevented in ester, mechanism is：Benzophenone derivates form stable freedom in irradiation process
Base, free radical or peroxy radical that makrolon strand is broken to form can be effectively captured, so as to cut off makrolon molecule
The photooxidation droping process of chain, reaches radiotolerant purpose.
In the molecular structure for having been reported that benzophenone ultraviolet absorbent in the prior art, it must contain at the ortho position of carbonyl
There is hydroxyl, the absorption 290-380nm ultraviolets of the benzophenone energy moderate strength containing a hydroxyl, protection is played to polymer
Effect, delays the loss of physical properties that turns yellow and reduce, available for light color and transparent article.Ultraviolet absorber and free radical of the present invention
Stabilizer is entirely different in the mechanism of action, as follows：Existing ultra-violet absorber, the hydrogen of hydroxyl and the oxygen shape of carbonyl on phenyl ring
Into intramolecular hydrogen bond, cyclic structure is formed, after ultraviolet energy is absorbed, hydrogen bond is destroyed, i.e., harmful ultraviolet is become
Heat energy discharges.And the benzophenone derivates that use of the present invention, not hydroxyl on phenyl ring（There is no the formation of intramolecular hydrogen bond
And destruction）, but stable free radical is formed in irradiation process, to capture the various free radicals of makrolon strand formation,
So as to suppress the degradation process of macromolecular chain.During irradiation sterilization, the energy of gamma-rays or electron beam is much larger than ultraviolet
Line, anti-xanthochromia of the disclosed benzophenone type ultraviolet absorbent on makrolon irradiation sterilization, antifog in the prior art
Change effect is not so good as benzophenone derivates of the present invention.
