Dimethiomethane (ti a tun mọ si methyl sulfide) jẹ agbo-ara Organic. Atẹle jẹ ifihan si awọn ohun-ini, awọn lilo, awọn ọna igbaradi ati alaye ailewu ti dimethylthiomethane:
Didara:
- Irisi: Omi ti ko ni awọ
- Òórùn: Ni kan to lagbara olfato ti hydrogen sulfide
- Solubility: Soluble ni ọpọlọpọ awọn olomi Organic gẹgẹbi ethanol ati ether
Lo:
- Gẹgẹbi epo: Dimethiomethane jẹ epo-ara ti o ṣe pataki ti o le ṣee lo lati tu ati sọ awọn agbo-ara Organic di mimọ.
- Kolaginni Kemikali: Nigbagbogbo a lo bi reagent ati agbedemeji ninu iṣelọpọ Organic, ati kopa ninu diẹ ninu alkylation, oxidation, sulfidation ati awọn aati miiran.
Awọn ohun elo polima: Dimethylthiomethane tun le ṣee lo fun ọna asopọ agbelebu ati iyipada ti awọn polima.
