Bis (2-5-Dimethyl-3-furyl) disulfide （CAS # 28588-73-0）

Intangiriro

3,3′-Dithiobis (2,5-dimethyl) furan, izwi kandi nka DMTD, ni urugimbu rwa organosulfur. Ibikurikira nintangiriro kuri bimwe mubintu byayo, imikoreshereze, uburyo bwo gukora, namakuru yumutekano:

Ubwiza:

- Kugaragara: DMTD ni ibara ritagira ibara ryumuhondo ryoroshye rifite impumuro idasanzwe.

- Gukemura: DMTD ntishobora gushonga mumazi kandi igashonga mumashanyarazi nka alcool, ethers, na hydrocarbone.

Koresha:

- DMTD ikoreshwa nka yihuta yihuta kandi ikingira. Irashobora gukoreshwa mu nganda za reberi kugirango iteze imbere reaction ya volcanisation ya reberi no kunoza imbaraga, kwambara no kurwanya gusaza ibicuruzwa bya reberi.

Uburyo:

- DMTD irashobora gutegurwa nigisubizo cya dimethyl disulfide (DMDS) hamwe na dimethylfuran. Igisubizo kibera ku bushyuhe bwo hejuru (150-160 ° C) kandi bigahungabana hamwe nizindi ntambwe zo gutunganya kugirango ubone ibicuruzwa byiza.

Amakuru yumutekano:

- DMTD ifite impumuro mbi kandi igomba kwirindwa kumara igihe kinini.

- Mu bicuruzwa bituruka mu nganda, guhumeka neza hamwe ningamba zo gukingira umuntu nka gants, indorerwamo, n imyenda ikingira igomba kuba ihari.

- DMTD irakaza uruhu n'amaso, irinde rero guhura nayo.

- Mugihe ubitse kandi ukoresha, irinde ubushyuhe bwinshi, fungura umuriro, hamwe na okiside.
