1.O mea tau vailaau:
Suavai manino samasama samasama.E iai le manogi leaga.E le mafai ona solu i le vai ma e mafai ona faʻafefiloi ma le ethanol, eter, ma le acetic acid.
2. Fa'amoemoe:
Fa'aaogaina e fai ma sui fa'agasolo mo solvents, catalysts, pesticide intermediates, coking inhibitors, etc. Dimethyl disulfide e tali atu i le cresol e maua ai le 2-methyl-4-hydroxy anisulfide, ona fa'afefiloi ai lea ma le O, O-dimethyl phosphoryl sulfide chloride i le Chemicalbook alkaline auala e maua ai Fenthion.Ose vaila'au phosphorus e sili ona lelei ma e maualalo ona o'ona ma e sili ona lelei le fa'atonutonuina o fa'ama'i araisa, anufe fatu fatu soya, ma togo gadfly.E mafai fo'i ona fa'aaogaina e fai ma vaila'au fa'afoma'i e fa'aumatia ai ilo o povi ma utu puipui povi.
3. Fausia auala:
①E maua mai i le tali atu o le Dimethyl sulfate ma le Sodium sulfide.Fa'aopoopo le pauta o le sulfur i totonu o le vaifofo o le Sodium sulfide i lalo o le fa'aosoina, fa'ae'e le vevela i le 80-90 ℃, tali mo le 1h, ma fa'aititia le vevela ole Chemicalbook ile 30 ℃;O le Dimethyl sulfate e pa'ū i totonu o le ulo tali, o le tali e faʻaauau mo le 2h, ona faʻafefe ai lea, tu mo le faʻapipiʻiina.Ina ua uma ona tuueseeseina le otaota alkali ava, o le oloa maeʻa maua e ala i distillation.
②Dimethyl disulfide o loʻo faʻapipiʻiina e le Dimethyl sulfate metotia i pisinisi.
Na2S+S → Na2S2Na2S2+(CH3) 2SO4 → CH3SSCH3+Na2SO4
Tuu le Sodium sulfide ma vai i totonu o le ulo tali, vevela, pulea le vevela i le 50 ~ 60 ℃ e faʻamavae ai le sulfurized Chemicalbook sodium, ona faʻaopopo lea o le sulfur equimolar i vaega, faʻamafanafana mo le 1h, faʻamafanafana i le 45 ℃, amata. pa'u le Dimethyl sulfate, taofi le vevela tali i le va o le 40 ~ 45 ℃, fa'amafanafana mo le 1h pe a uma ona fa'aopoopo, ona fa'amama lea o le oloa Dimethyl disulfide.E le gata i lea, o le Dimethyl disulfide e mafai foi ona faʻapipiʻiina e le metotia methyl mercaptan.
③E gaosia e ala i le tali atu o le iodomethyl magnesium ma le Disulfur dichloride.E faia i le tali atu o le sodium disulfide ma le sodium methylsulfate.O le Methyl Sodium thiosulfate e saunia e ala i le tali atu o Bromomethane ma le Sodium thiosulfate, ona faʻamafanafanaina lea.
4.Storage ma felauaiga uiga:
Ventilation ma le maualalo o le vevela faʻamago o le faleteuoloa;Teu ese ese mai oxidants ma acids
5.Tinei afi
Efuefu mamago, oneone mago, carbon dioxide, foam, 1211 mea e tineia ai
I le taimi nei, o loʻo faʻaauau pea ona tuʻuina atu e Jinan ZhongAn Industry Co., Ltd le DMDS i maketi tetele.Ia Setema o lenei tausaga, Jinan ZhongAn Industry Co., Ltd o le a faʻalauteleina la matou laina gaosiga e faʻafetaui ai manaʻoga o le tele o tagata faʻatau.Matou te faʻafeiloaʻi tagata faʻatau mai le lalolagi atoa e faʻatalanoa i matou.Ua maua foi e le matou kamupani le tusipasi ISO9001.Faamolemole ia mautinoa o le tulaga lelei o oloa.
