I-Antioxidant 1520

I-AO1520

I-Antioxidant 1520 (2, 4-BIS (N-OCYLLTHIOMELYLENELY) -6-Huthylphenol) Uhlobo olusha lwe-antioxidant, i-phenol hydroxyl ingabanjwa ama-hydroperoch, ingaba nomphumela we-antioleric, ingasetshenziswa ama-oxygen, njll., Ukuvimbela umoya-mpilo, ukushisa, ukukhanya noma ukulimala kwemisebe ye-radiation ephezulu ye-organic. Ikakhulu, i-antioxidant 1520 ingasetshenziswa ukumelana nokuguga oxidativation ngesikhathi sokugcina impahla ehlukahlukene ye-eladiene, ukuvikela ukuqina kokugcina ku-styrene buber, ukuvimba ukuqina kokugcina ku-styrene buberterene, ukuvikela ukuqina kokugcina ku-i-Styrene Buber, ukuvikela ukuguga ngaphansi kwezimo ku-isoprene styrene block block copolymers, ukuvikela Ukwakheka kwe-gel kuma-elastomers kanye nokuhlanganiswa kombala wangasese ngesikhathi sokugcina nokuhamba.

Isicelo

I-Antioxidant 1520 iyisisindo esisha esiphakeme se-antioxidant, esetshenziswa kakhulu enjoloba ye-buthadiene, i-styrene buthane, irabha ye-ethrlene, i-antioxidastic, umphumela we-antioxidastic, ungathuthukisa ukuqina kwamapulasitiki noma ipulasitiki yokwenziwa. Kuyinto antioxidant, ebona ukuguqulwa kwemikhiqizo yenjoloba kusuka ku-Universal kuya kokuluhlaza.

Indlela ye-Synthesis

Njengamanje, indlela yokuhlanganiswa ye-antioxidant 1520 ikakhulukazi i-Mannich Alkali indlela, okungukuthi, o-methylphenol, n-OCYLLMECTAN, i-OcTreamDehyde noma i-paraformaldehyde etholwe nguMannich reaction.

Indlela engenhla ye-synthesis ifaka izindlela ezimbili zenqubo ekusebenzeni kwangempela, eyodwa yi-O-Methylphenol kanye ne-polytformDehyhehyde, bese usabela nokwakheka kwe-antioxinant ngo-1520, bese uqhubeka nokuhlanza kwendlela yomkhiqizo, eyaziwa ngokuthi yi- indlela yezinyathelo ezimbili. Ukufundwa okujwayelekile kufaka phakathi i-US3832328, EP4228973A1, I-US5116894, njll.

Indlela eyenziwe kahle ye-antioxidant 1520 iqukethe lezi zinyathelo ezilandelayo:

1) O-Cresol, N-OCYLLMERCAPAN, DORDEHYDede, i-DIETAnolamine futhi i-solvent yengezwe ku-reaction, bese i-acid yengezwe ukuguqula i-PH ku-1-5 ukuze uphendule;

2) Ukupholisa nokuma ukuhambisa, ukukhipha isigaba samanzi esiphansi kusuka endaweni ephansi ye-reactor, bese engeza iodomethane ne-cui, bese uphinda kabusha ukwenza ukusabela;

3) Okupholile, hlunga ukuze ususe udaba lwe-insoluble, engeza inani elifanele le-formic acid futhi uphinde uphinde ube ngu-30-60 ℃, uvuse;

4) Ngemuva kokugeza ngamanzi, i-vacuum distillation, ukomisa, ukulungele.

Qingdao yihoo polymer technology co. ltd. uzibophezele ekukhiqizweni nasekuhlinzekweni kwezinhlobonhlobo zezithasiselo ezisebenzayo ezisetshenziswa kumapulasitiki kanye nezembatho. Izinhlobo Zomkhiqizo zihlanganisa ama-antioxidants, abaqinisi abakhanyisi, ababukeli be-UV, amalangabi ama-retaardants, njll., Futhi imikhiqizo ithole amakhasimende angaphezu kwe-100 phesheya kwezilwandle amethemba.
