Pakati pavo, nzira yekugadzirira yepakati 4-formamide-2,2,6, 6-tetramethylpiperidine ndeye: 2,2,6, 6-tetramethylpiperidine, formamide, Lewis acid catalyst, kusunga alkali agent, yakaiswa mukupisa kwemhepo pasi pemhepo. kumanikidzwa kwe1-24h.Chigadzirwa chacho chaiwanikwa mushure mokukuchidzira, kutonhora, kugeza, kusefa, uye kuomesa.
Iyo synthesis process yekugadzirwa iri nyore uye iri nyore kushanda, uye iyo mushure-kurapa iri nyore;izvo zvinodiwa mbishi, catalysts uye solvents zviri nyore kuwana.Iyo yose nzira inowirirana nemitemo yehupfumi, yakachengeteka uye yakasununguka, uye chibereko chechigadzirwa chakakwirira.
Nzira yekugadzirira yekudzivisa amine ultraviolet absorber
PATENT NUMBER: ZL201910576883.3
ABSTRACT
Iyo yakagadzirwa inoburitsa nzira yekugadzirira yakavharwa amine uv absorber: sanganisa malonic acid uye pentamethylpiperidol, wedzera toluene se solvent, wedzera catalyst, uye ita pa 100 ℃-110 ℃ kwe6h.Kuita kwakamiswa apo malonic acid yemukati yaive yakaderera pane 1%.Donhedza tembiricha kusvika pa50 ℃, wedzera mvura yakasvibiswa, simbisa kwe30min, wobva wawedzera huwandu hwakakwana hwecyclohexane neanisaldehyde, kurunga nekunyungudutsa, wedzera piperidine neacetic acid, kupisa kusvika 70 ℃ -80 ℃ kuti uite, uye paradzanisa mvura inogadzirwa. mukuita maitiro.Kuita kwakamiswa apo iyo anisaldehyde yemukati yaive yakaderera pane 1% muchikamu chemvura.Mhinduro yekupindura yakatonhodzwa kusvika ku5 ℃ uye yakasimudzwa kwe1h kusvika iyo yakasimba yaparadzaniswa zvachose.Mushure mekusefa, kuita kwakacheneswa nekatatu huwandu hweethanol uye yakawana chigadzirwa.
Kupisa kweiyo yakavharidzirwa amine uv absorber mukugadzirisa maitiro haisi yakakwirira kudarika 110 ℃;kugadzirisa kugadzirisa kune unyoro;maitiro ekuita ari nyore kudzora;uye kuchena kwechigadzirwa kwakakwirira;Iyo yekutanga reaction system haina hanya nemvura, uye inongoda kuburitsa mvura muhurongwa kana kuita kwave pedyo nekupedzwa, izvo zvinochengetedza maitiro ekushanda.
Chigadzirwa uye nzira yekugadzirira ye-multi-effect thiether bisphenol acrylat antioxidant
PATENT NUMBER: ZL201910569404.5
ABSTRACT
Phenol acrylate multi-effect antioxidant mamorekuru ane ese ari maviri makuru eakavharira phenol antioxidant anoshanda mapoka, anobatsira antioxidants thioether bond uye kabhoni inotorwa yemahara radicals basa re acrylic phenolic ester chimiro, iyo inounza katatu mhedzisiro syncretic mukugadzira uye kushandiswa kwepolymer zvinhu.Izvi zvingave zvirinani kudzivirira zvinhu zvepolymer, kudzivirira zvigadzirwa zvekuora uye kuchembera, kugadzirisa kusaita zvakanaka kana imwechete basa antioxidant rinoshandiswa pane polymer zvinhu.Zvichakadaro, iyo inoenderana gadziriro yekuita tembiricha uye kushandiswa kwesimba kwakadzikira, uye ne-chigadzirwa kusefa kunogona kubviswa pasina tsvina yemvura, uye kudzokorodza solvent, saka maitiro ari eco-hushamwari.
Nzira yekugadzirira yekuchena kwepamusoro pentaerythritol plastiki yekubatsira
PATENT NUMBER: 201910447473.9
ABSTRACT
Iyo yakagadzirwa inoburitsa nzira yekugadzirira yekuchena kwepamusoro pentaerythritol purasitiki yekubatsira, umo matanho ari anotevera: sanganisa zvinoshanda zvinoriumba uye pentaerythritol, kupisa kusvika ku100-150 ℃ uye kumutsa kwe15min;wedzera dioctyl tin oxide, kupisa kusvika 170-190 ℃ mushure mekuchenesa nitrogen, enderera mberi nekuita kusvikira chikamu chemvura chekutsvaga chigadzirwa chisisawedzere;donhedza tembiricha kusvika 150 ℃, wedzera xylene, ramba uchidonhedza tembiricha kusvika 100 ℃, wobva wawedzera low molecular monic acid aqueous solution, fambisa pa100 ℃ kwe1h, kudonha kusvika kukamuri tembiricha;wedzera methanol, kurunga kwe3-5h, uye yakasimba coarse chigadzirwa chakasefa kuti chiwane icho chakachena chigadzirwa mushure mekuitazve crystallization ne toluene.
Mushure mekuita kwapera, iyo yakaderera-molecular-monic asidhi yakawedzerwa zvakananga mune reactant kuti iite esterification reaction neinodzikisirwa uye trisubstituted tsvina mune reactant, kuitira kunyungudutsa tsvina nekuzviparadzanisa kubva pachigadzirwa.Iyo nzira haidi kushandisa yakawanda yezvinonyungudutsa uye akawanda recrystallization mashandiro, uye ine yakanaka yekusachena yekubvisa maitiro.
Nzira yekugadzirira ye6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene
PATENT NUMBER: ZL201610332457.1
ABSTRACT
Iyo yakagadzirwa inozivisa nzira yekugadzirira ye6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene.
Nzira yacho inosanganisira: kubatanidza maitiro: methyl o-bromobenzoate inosanganiswa ne9, 9-dimethyl su-2-boric acid kuti ibudise mishonga sezvinoratidzwa muFormula M-1;Addition reaction: chidimbu chinoratidzwa muFormula M-1 inowedzerwa nemethyl magnesium bromide, uyezve hydrolyzed kuti iite musanganiswa unoratidzwa muhuwandu hweM-2;Cyclization reaction: pamberi peasidhi, musanganiswa unoratidzwa mufomula M-2 inotenderera uye inoshandurwa kuita 6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene sezvakaratidzwa mufomula M. .
Maererano nekugadzirira nzira yekugadzirwa, nzira yacho iri nyore uye iri nyore kushanda;Zvokubikisa zvinodiwa zvinowanika nyore pamutengo wakaderera;Goho i77 ~ 88%, yakakodzera kugadzirwa kwakakura.
