I-PATENT INOMBOLO: ZL201910576883.3
ABSTRACT
Ukusungulwa kuveza indlela yokulungiselela isimunyisi se-amine UV esivinjiwe: hlanganisa i-malonic acid ne-pentamethylpiperidol, engeza i-toluene njengesincibilikisi, engeza i-catalyst, bese usabele ku-100℃-110℃ amahora angu-6.Ukusabela kuye kwamiswa lapho okuqukethwe kwe-malonic acid kungaphansi kuka-1%.Yehlisa izinga lokushisa libe ku-50 ℃, engeza amanzi angcolile, ugovuze i-30min, bese wengeza inani elanele le-cyclohexane ne-anisaldehyde, gudluza futhi uncibilike, engeza i-piperidine ne-acetic acid, ukushisa kufikela ku-70℃-80℃ ukuze uphendule, bese uhlukanisa amanzi akhiqiziwe. enqubweni yokusabela.Ukusabela kuye kwamiswa lapho okuqukethwe kwe-anisaldehyde kwakungaphansi kuka-1% esigabeni soketshezi.Isixazululo sokusabela sipholile sibe ngu-5 ℃ futhi sixutshwe ihora elingu-1 kuze kube yilapho okuqinile kuhlukaniswa ngokuphelele.Ngemuva kokuhlunga, ukusabela kwahlanzwa ngenani le-ethanol eliphindwe izikhathi ezi-3 futhi kwathola umkhiqizo.
Izinga lokushisa le-amine uv absorber elivinjiwe ohlelweni lokulungisa alikho ngaphezu kuka-110 ℃;ukulungiswa kokusabela kumnene;inqubo yokusabela kulula ukuyilawula;futhi ubumsulwa bomkhiqizo buphakeme;Isistimu yokusabela kusenesikhathi ayizwelani namanzi, futhi idinga kuphela ukukhipha amanzi ohlelweni lapho ukusabela sekuseduze nokuqedwa, okusindisa inqubo yokusebenza.
Umkhiqizo kanye nendlela yokulungiselela ye-multi-effect bisphenol acrylat antioxidant
I-PATENT INOMBOLO: ZL201910569404.5
ABSTRACT
I-Phenol acrylate multi-effect antioxidant molecules iqukethe womabili amaqembu asebenzayo e-phenol antioxidant avinjiwe, isibopho se-antioxidant esisizayo kanye nomsebenzi wama-radicals wamahhala wokubamba ikhabhoni wesakhiwo se-acrylic phenolic ester, esiletha umphumela ophindwe kathathu wokuvumelanisa kukho kokubili ukukhiqizwa nokusetshenziswa kwezinto ze-polymer.Lokhu bekuzovikela kangcono izinto ze-polymer, kugweme imikhiqizo yokuwohloka nokuguga, kuxazulule ukusebenza kabi lapho kusetshenziswa umsebenzi owodwa we-antioxidant ezintweni ze-polymer.Phakathi naleso sikhathi, izinga lokushisa elihambisanayo lokulungiselela inqubo yokusabela kanye nokusetshenziswa kwamandla kuphansi, futhi ukuhlunga ngomkhiqizo kungasuswa ngaphandle kwamanzi angcolile, kanye ne-solvent yokuvuselela kabusha, ngakho inqubo i-eco-friendly.
Indlela yokulungiselela ukuhlanzeka okuphezulu kwe-pentaerythritol plastic auxiliary
I-PATENT INOMBOLO: 201910447473.9
ABSTRACT
Ukusungulwa kuveza indlela yokulungiselela ukuhlanzeka okuphezulu kwepulasitiki ye-pentaerythritol, lapho izinyathelo zimi kanje: hlanganisa izingxenye ezisebenzayo kanye ne-pentaerythritol, ukushisa kufika ku-100-150 ℃ bese ugoqa i-15min;engeza i-dioctyl tin oxide, ukushisa ku-170-190℃ ngemva kokukhishwa kwe-nitrogen, qhubeka nokusabela kuze kube yilapho okuqukethwe komkhiqizo wokuthola uketshezi kungasakhuli;yehlisa izinga lokushisa libe ngu-150 ℃, engeza i-xylene, qhubeka nokwehlisa izinga lokushisa libe ngu-100 ℃, bese wengeza isixazululo esinamanzi se-monic acid ephansi, ugovuze ku-100 ℃ ihora elingu-1, uphonsa ekamelweni lokushisa;engeza i-methanol, gudluza amahora angu-3-5, futhi umkhiqizo oqinile wahlungwa ukuze uthole umkhiqizo ohlanzekile ngemva kokwenziwa kabusha kwekristalu nge-toluene.
Ngemva kokuqedwa kokusabela, i-low-molecular-monic acid yengezwe ngokuqondile ku-reactant ukuze kwenziwe ukusabela kwe-esterification ngokungcola okugudlukayo nokuthathelwe indawo kathathu ku-reactant, ukuze kuncibilike ukungcola futhi kukuhlukanise nomkhiqizo.Indlela ayidingi ukusebenzisa inani elikhulu lama-solvents kanye nemisebenzi eminingi ye-recrystallization, futhi inomphumela omuhle wokususa ukungcola.
Indlela yokulungiselela ye-6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene
INOMBOLO YOBULUNGISWA: ZL201610332457.1
ABSTRACT
Ukusungulwa kuveza indlela yokulungiselela i-6,6,12, i-12-tetramethyl-6, i-12-dihydroindene [1,2-b] i-fluorene.
Indlela ihlanganisa: ukusabela kokuhlanganisa: i-methyl o-bromobenzoate ihlanganiswe ne-9, i-9-dimethyl su-2-boric acid ukuze ikhiqize izinhlanganisela njengoba kuboniswe ku-Formula M-1;Ukusabela kokwengeza: i-compound eboniswe ku-Formula M-1 yengezwe nge-methyl magnesium bromide, bese i-hydrolyzed ukuze yakhe inhlanganisela ekhonjiswe kufomula M-2;Ukusabela kwe-Cyclization: lapho kukhona i-asidi, i-compound ekhonjiswe kufomula M-2 ihanjiswa ngebhayisikili futhi iguqulwa ibe yi-6,6,12, 12-tetramethyl-6, 12-dihydroindene [1,2-b] fluorene njengoba kuboniswe kufomula M. .
Ngokwendlela yokulungiselela yokusungulwa, inqubo ilula futhi kulula ukuyisebenzisa;Izinto zokusetshenziswa ezidingekayo zitholakala kalula ngezindleko eziphansi;Isivuno singama-77 ~ 88%, alungele ukukhiqizwa okukhulu.
