Synthesis thiab Properties ntawm Vanillyl Cawv raws li High Performance Dielectric Materials
Nrog rau kev loj hlob sai ntawm thaj chaw xws li 5G kev sib txuas lus, kev txawj ntse, thiab lub zog tshiab, qhov kev thov rau siab -cov ntaub ntawv dielectric kev ua tau zoo tau dhau los sai heev. Traditional dielectric cov ntaub ntawv xws li barium titanate (BaTiO3) thiab polyvinylidene fluoride (PVDF) muaj siab dielectric tas li, tab sis lawv muaj teeb meem xws li siab dielectric poob, nyuaj ua, los yog tsis txaus yooj.
Yog li ntawd, txoj kev loj hlob ntawm tshiab dielectric cov ntaub ntawv uas ua ke siab dielectric tas li, tsis tshua muaj dielectric poob, zoo heev thermal stability, thiab txhua yam hloov tau los ua ib qho kev tshawb fawb hotspot. Vanillin cawv (4-hydroxy-3-methoxybenzyl cawv, CAS naj npawb 498-00-0) yog lub ntuj phenolic compound tsim los ntawm kev txo qis ntawm vanillin. Nws cov qauv molecular muaj phenolic hydroxyl (- OH) thiab methoxy (- OCH3) pawg, ua rau nws muaj cov tshuaj lom neeg tshwj xeeb thiab lub cev muaj zog.
Kev tshawb fawb tau pom tias phenolic hydroxyl pawg ntawm cov compound tuaj yeem koom nrog hydrogen bonding thiab chemical cross -linking reactions, thaum pawg methoxy tuaj yeem tswj cov molecular polarity, yog li cuam tshuam rau dielectric zog ntawm cov khoom. Tsis tas li ntawd, nws muaj biocompatibility, tsawg toxicity, thiab degradability, uas yog nyob rau hauv txoj kab nrog txoj kev loj hlob ntawm ntsuab chemistry.
Nws feem ntau muaj nyob rau hauv tubers ntawm orchid cog Gastrodia elata B1. thiab yog cov khoom muaj txiaj ntsig zoo hauv Gastrodia elata. Nws muaj cov nyhuv sedative tseem ceeb ntawm kev ua tau zoo, tuaj yeem txo cov kev ua haujlwm ntawm cov nas, ua kom lub sijhawm pw tsaug zog ntawm cyclohexene barbiturate sodium, thiab txhawb cov kua tsib lub zais zis. Cov tshuaj synthesis ntawm vanillin yuav tsum tau siv lub sij hawm ntev cov tshuaj tiv thaiv, ib tug loj npaum li cas ntawm cov kuab tshuaj, tsis tshua muaj conversion tus nqi, thiab tus nqi siab. Yog li ntawd, yuav tsum tau ceev nrooj los tsim cov txheej txheem thev naus laus zis tshiab los tsim cov vanillin.
Ib txoj hauv kev npaj vanillin los ntawm kev txo qis vanillin nrog cov kab mob, suav nrog:
(1) Siv lub nplhaib ntawm Acetobacter los ntawm agar slant kab lis kev cai nruab nrab siv los khaws cov kab mob thiab hloov mus rau cov kua noob kab lis kev cai nruab nrab. Incubate ntawm 20-30℃rau 12-24 teev kom qhib cov kab mob;
(2) Hloov cov noob ua kua rau hauv cov kua fermentation nruab nrab ntawm qhov ntim feem pua ntawm 6-10%, thiab incubate on ib shaker ntawm 20-30℃los yog cia nws sawv ntsug rau 12-48 teev;
(3) Thaum muaj ntau cov tshuaj flocculent tsim nyob rau hauv cov kua fermentation nruab nrab, ib tug lim thiab sterilized vanillin tov yog ntxiv rau nruab nrab kom ua tiav qhov kawg concentration ntawm 0.1-3.0 mmol / L. Tom qab co lossis sawv ntawm 20-35℃rau 0.5-7 hnub, vanillin cawv tau txais.
Kev hloov pauv tus nqi ntawm qhov kev tsim tawm tam sim no yog qhov siab, ncav cuag 50-98%. Cov tshuaj tiv thaiv yog me me, ib puag ncig tus phooj ywg, thiab muaj kev cia siab rau kev thov.
Ntawm lawv, cov khoom ntawm cov kua noob kab lis kev cai nruab nrab thiab kua fermentation kab lis kev cai nruab nrab nyob rau hauv cov kauj ruam (I) thiab (2) yog: mannitol, qabzib, sucrose, glycerol los yog fructose 25g, peptone los yog tryptone 3g, poov xab extract 5g, dej IL, pH 3.5-7.5121℃C rau 20 feeb; Xwb, nws tuaj yeem yog: 20-100g ntawm mannitol, qabzib, mos lwj qab zib, glycerol lossis fructose, 5g ntawm poov xab extract, 5g ntawm peptone los yog tryptone, 15g citric acid, 2.7g ntawm Na2HPO4, dej IL, pH 3.5-7.512.
