Hoʻolauna
ʻO cis,cis-1,3-cyclooctadiene (cis, cis-1,3-cyclooctadiene) he mea hoʻohuihui mea ola me ke ʻano kemika C8H12. Loaʻa iā ia ʻelua mau mea paʻa paʻa paʻa ʻelua a me kahi ʻano apo apo ʻewalu lālā.
ʻO cis,cis-1,3-cyclooctadiene he wai kala ʻole me kahi ʻala kūikawā. Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau, e like me ka ethanol, tetrahydrofuran a me dimethylformamide.
ma kemika, cis,cis-1,3-cyclooctadiene e hoʻohana pinepine ʻia e like me nā ligands o nā pūhui hoʻohui e komo i ka synthesis o nā pūhui metala hoʻololi e like me ka platinum a me ka molybdenum. Hiki iā ia ke hana ma ke ʻano he catalyst precursor i ka hydrogenation o nā pūhui unsaturated. Eia kekahi, hiki ke hoʻohana ʻia ka cis,cis-1,3-cyclooctadiene ma ke ʻano he synthetic intermediates o nā mea ʻala a me nā mea ʻala.
ʻO cis,cis-1,3-cyclooctadiene ka nui o nā ʻano hoʻomākaukau ʻelua: ʻo kekahi ma o ka hopena photochemical, ʻo ia hoʻi, ʻike ʻia ʻo 1,5-cycloheptadiene i ke kukui ultraviolet, a ʻo cis, cis-1,3-cyclooctadiene i hana ʻia ma o ka hopena. ʻO kekahi ala ʻē aʻe ma ka metal catalysis, no ka laʻana ma ka pane ʻana me kahi catalyst metala e like me palladium, platinum, etc.
E pili ana i ka ʻike palekana o cis,cis-1,3-cyclooctadiene, he wai wela ia me nā hiʻohiʻona hiki ke ahi ma ke ʻano o ka mahu a i ʻole ke kinoea. I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e mālama ʻia e pale aku i ka hoʻopili ʻana me nā lapalapa ākea, nā wela kiʻekiʻe a me ka oxygen. I ka manawa like, hiki i ka hoʻopili ʻana me ka ʻili, nā maka a me ka ʻāpana hanu o cis,cis-1 a me 3-cyclooctadiene ke hoʻonāukiuki a me ka pōʻino. No laila, pono e hoʻohana ʻia nā mīkina lima pale a me nā goggles i ka wā e hoʻohana ai, a pono e mālama ʻia kahi wahi hana maikaʻi.
