Hoʻolauna
ʻO Dimethyl disulfide (DMDS) he mea hoʻohuihui mea ola me ke ʻano kemika C2H6S2. He wai waihoʻoluʻu ʻole me kahi ʻala ʻala ʻē aʻe.
He ʻokoʻa ka hoʻohana ʻana o DMDS i ka ʻoihana. ʻO ka mea mua, hoʻohana maʻamau ia ma ke ʻano he catalyst sulfidation, ʻoi aku hoʻi i ka ʻoihana ʻaila e hoʻomaikaʻi i ka pono o ka hoʻomaʻemaʻe a me nā kaʻina aila ʻē aʻe. ʻO ka lua, he mea fungicide koʻikoʻi ʻo DMDS a me nā insecticide hiki ke hoʻohana ʻia i ka mahiʻai a me ka horticulture, e like me ka pale ʻana i nā mea kanu a me nā pua mai nā germs a me nā pests. Eia kekahi, hoʻohana nui ʻia ʻo DMDS ma ke ʻano he reagent i ka synthesis kemika a me nā hopena synthesis organik.
ʻO ke ala nui o ka hoʻomākaukau ʻana i ka DMDS ma o ka hopena o carbon disulfide a me methylammonium. Hiki ke hana ʻia kēia kaʻina hana i nā wela kiʻekiʻe, e koi pinepine i ka hoʻohana ʻana i nā catalysts e hoʻomaʻamaʻa i ka hopena.
E pili ana i ka ʻike palekana, he wai wela ka DMDS a he ʻala ʻala. Pono e ʻaʻahu ʻia nā mea pale kūpono e like me nā mīkina lima, nā makaaniani palekana, a me nā lole pale i ka wā e lawelawe ai a hoʻohana ʻia. I ka manawa like, pono e mālama ʻia mai ke ahi a me nā kumu wela e pale ai i ke ahi a pahū paha. No ka mālama ʻana a me ka lawe ʻana, pono e hoʻokomo ʻia ʻo DMDS i loko o kahi pahu hau a mālama ʻia i kahi maloʻo, maloʻo, maikaʻi ka makani, mamao mai nā mea ʻona a me nā kumu ahi. I ka hopena o kahi leak ulia, pono e lawe koke ʻia nā hana hoʻoneʻe kūpono a pono e hōʻoia i ka ea kūpono.
