Profil Reaktivitas |
Organosulfida, kayata Dimethyl sulfide, ora kompatibel karo asam, senyawa diazo lan azo, halokarbon, isokyanat, aldehid, logam alkali, nitrida, hidrida, lan agen pangurangan sing kuwat. Reaksi karo bahan kasebut ngasilake heatand ing pirang-pirang kasus gas hidrogen. Akeh senyawa kasebut bisa mbebasake hidrogensulfida nalika dekomposisi utawa reaksi karo asam. Dimethyl sulfide kanthi cepet nggawe komposisi dibenzoyl peroksida kanthi eksplosif yen ora ana pelarut, [J. Org.Chem., 1972, 37, 2885]. Sulfida uga bosok xenon difluorida sacara eksplosif ing suhu sekitar, [J, Chem Soc., 1984, 2827]. Interaksi Dimethyl sulfide lan oksigen jeblugan ing 210 ° C lan ndhuwur, [Atmos.En environment., 1967, 1, 491-497]. Jeblugan sing telat kedadeyan ing sistem sing ngemot asam nitrat, Dimethyl sulfide, lan 1, 4-dioxane, malah kanthi pendinginan karo nitrogen cair, [Chem. Abs, 1972, 76, 13515]. |

Profil Keamanan |
Byinhalation racun. Moderat beracun amarga asupan. Kulit lan iritasi mripat abot. Bebaya geni sing mbebayani banget nalika kena panas utawa geni. Bahan peledak ing bentuk uap nalika kena panas utawa geni. Bisa reaksi kanthi kuat kanthi bahan oksidasi. Kanggo nglawan kobongan, gunakake bahan kimia CO2, garing. Nalika todecomposition sing digawe panas, ngetokake SOx sing bisa beracun lan bisa njeblug. Deleng ugaSULFIDES. |

Metode Pemurnian |
Murni dimethylsulfide liwat kompleks klorida Hg (II) kanthi mbubarake 1 mol Hg (II) Cl2 in1250mL saka EtOH lan alon-alon nambahake larutan alkohol Me2S sing nggodhok, menehi rasio sing pas kanggo 2 (CH3) 2S.3HgCl2. Sawise rekristalisasi kompleks nganti titik leleh konstan, kompleks 500g dipanasake kanthi 250mL concHCl ing banyu 750mL. Sulfida dipisahake, dicuci nganggo banyu, lan dikeringake nganggo CaCl2 lan CaSO4. Pungkasan, disaring ing tekanan saka sodium sing suda. Ati-ati kudu ditindakake (hood fume efisien) amarga ODOR sing BESAR banget. [Beilstein 1 IV 1275.] |
