ABSTRACT
Njira yokonzekera yolepheretsa kuwala kwa amine stabilizer N,N'-bis (2,2,6, 6-tetramethyl-4-piperidyl)-N,N'-diuronic alkyl diamine ili motere: 4-formamide-2,2 , 6, 6-tetramethylpiperidine ndi dibromothane zinalimbikitsidwa ndi reflux ndi chothandizira kwa 1-24h, ndipo madzi anawonjezeredwa pang'onopang'ono mwamsanga.Mankhwalawa ankawapeza atawasonkhezera, kuziziritsa, kuchapa, kusefa, ndi kuumitsa .
Pakati pawo, njira yokonzekera yapakatikati ya 4-formamide-2,2,6, 6-tetramethylpiperidine ndi: 2,2,6, 6-tetramethylpiperidine, formamide, Lewis acid chothandizira, kumanga alkali wothandizila, adayikidwa mu Kutentha kwamlengalenga. kuthamanga kwa 1-24h.Mankhwalawa ankapezedwa pambuyo posonkhezera, kuziziritsa, kuchapa, kusefa, ndi kuumitsa.
Kaphatikizidwe kakupangidwirako ndi kophweka komanso kosavuta kugwiritsa ntchito, ndipo chithandizo chotsatira ndichosavuta;zofunikira zopangira, zosungunulira ndi zosungunulira ndizosavuta kupeza.Njira yonseyi ikugwirizana ndi mfundo zachuma, zotetezeka komanso zachilengedwe, ndipo zokolola zamtengo wapatali zimakhala zazikulu.
Njira yokonzekera yolepheretsa amine ultraviolet absorber
NUMBER YA PATENT: ZL201910576883.3
ABSTRACT
Zomwe zimapangidwazo zimawulula njira yokonzekera yotsekera amine uv absorber: sakanizani malonic acid ndi pentamethylpiperidol, kuwonjezera toluene monga zosungunulira, kuwonjezera chothandizira, ndikuchitapo pa 100 ℃ -110 ℃ kwa 6h.Zomwe zidayimitsidwa pamene malonic acid okhutira anali otsika kuposa 1%.Kusiya kutentha kwa 50 ℃, kuwonjezera madzi deionized, chipwirikiti 30min, ndiye kuwonjezera okwanira kuchuluka kwa cyclohexane ndi anisaldehyde, chipwirikiti ndi kupasuka, kuwonjezera piperidine ndi asidi asidi, kutentha kwa 70 ℃ -80 ℃ kuchita, ndi kulekanitsa madzi kwaiye. mukuchitapo kanthu.Zimene anasiya pamene anisaldehyde zili otsika kuposa 1% mu madzi gawo.Njira yothetsera vutoli idakhazikika mpaka 5 ℃ ndikugwedezeka kwa 1h mpaka cholimbacho chidalekanitsidwa.Pambuyo kusefera, zimene anachita anayeretsedwa ndi 3 kuchuluka kwa Mowa ndi kupeza mankhwala.
Kutentha kwa chotchinga cha amine UV cholepheretsa pokonzekera sikuposa 110 ℃;zomwe kusintha ndi wofatsa;zochita ndondomeko n'zosavuta kulamulira;ndipo mankhwala chiyero ndi mkulu;Dongosolo loyambirira la machitidwe silimakhudzidwa ndi madzi, ndipo limangofunika kutulutsa madzi m'dongosololi pamene zotsatira zatsala pang'ono kutha, zomwe zimapulumutsa ntchitoyo.
Mankhwala ndi njira yokonzekera ya multi-effect bisphenol acrylat antioxidant
NUMBER YA PATENT: ZL201910569404.5
ABSTRACT
Phenol acrylate multi-effect antioxidant mamolekyulu ali ndi magulu onse awiri omwe amalepheretsa phenol antioxidant ntchito, othandizira ma antioxidants thioether bond ndi carbon capture free radicals ntchito ya acrylic phenolic ester structure, yomwe imabweretsa kuphatikizika katatu pakupanga komanso kugwiritsa ntchito zida za polima.Izi zikanakhala bwino kuteteza zipangizo za polima, kupewa zinthu zowonongeka ndi kukalamba, kuthetsa kusagwira bwino ntchito pamene antioxidant imodzi imagwiritsidwa ntchito pazinthu za polima.Nthawiyi, lolingana kukonzekera ndondomeko anachita kutentha ndi mowa mphamvu ndi otsika, ndipo ndi mankhwala kusefera akhoza kuchotsedwa popanda madzi zinyalala, ndi yobwezeretsanso zosungunulira, kotero ndondomeko ndi Eco-wochezeka.
Njira yokonzekera yoyeretsa kwambiri pentaerythritol pulasitiki wothandizira
PATENT NUMBER: 201910447473.9
ABSTRACT
Kupangidwa kumawulula njira yokonzekera chiyero chapamwamba cha pentaerythritol chothandizira pulasitiki, momwe masitepe ali motere: kusakaniza zigawo zogwira ntchito ndi pentaerythritol, kutentha mpaka 100-150 ℃ ndikuyambitsa 15min;onjezani dioctyl tin oxide, kutentha mpaka 170-190 ℃ mutatha kuyeretsedwa kwa nayitrogeni, pitilizani zomwe zikuchitika mpaka gawo lamadzimadzi lodziwikiratu silikuwonjezekanso;tsitsani kutentha mpaka 150 ℃, onjezani xylene, pitilizani kutsitsa kutentha mpaka 100 ℃, kenaka yikani monic acid amadzimadzi, yambitsani 100 ℃ kwa 1h, kutsika kutentha;onjezani methanol, kusonkhezera kwa 3-5h, ndipo cholimba coarse mankhwala ankasefedwa kupeza mankhwala koyera pambuyo kachiwiri crystallization ndi toluene.
Pambuyo zimene anamaliza, ndi otsika-maselo-monic asidi anawonjezera mwachindunji mu reactant kuchita esterification anachita ndi displaceable ndi trisubstituted zonyansa mu reactant, kuti kupasuka zosafunika ndi kuwalekanitsa ndi mankhwala.Njirayi sayenera kugwiritsa ntchito zosungunulira zambiri ndi ntchito zambiri za recrystallization, ndipo zimakhala ndi zotsatira zabwino zochotsa zonyansa.
Njira yokonzekera 6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene
NUMBER YA PATENT: ZL201610332457.1
ABSTRACT
Zomwe zimapangidwazo zimawulula njira yokonzekera 6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene.
Njirayi imaphatikizapo: kugwirizanitsa zochita: methyl o-bromobenzoate ikuphatikizidwa ndi 9, 9-dimethyl su-2-boric acid kuti apange mankhwala monga momwe akuwonetsera mu Fomula M-1;Zowonjezera zomwe zikuwonetsedwa mu Fomula M-1 zimawonjezeredwa ndi methyl magnesium bromide, kenako ndi hydrolyzed kuti apange gulu lomwe likuwonetsedwa mu formula M-2;Cyclization reaction: pamaso pa asidi, pawiri yomwe ikuwonetsedwa mu formula M-2 imayendetsedwa ndikusinthidwa kukhala 6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene monga momwe zasonyezedwera mu formula M. .
Malingana ndi njira yokonzekera yopangidwira, ndondomekoyi ndi yosavuta komanso yosavuta kugwiritsa ntchito;Zopangira zofunika zimapezeka mosavuta pamtengo wotsika;Zokolola ndi 77 ~ 88%, zoyenera kupanga zazikulu.
