Ngā Āhuatanga Hua
Nō roto i ngā tioata ionic te hauwaiwai konutai, arā, he matū tote kei roto ko te hauwai he iona monovalent kino. Ina whakamahanatia, kāore e pumau, ka pirau, kāore e rewa, ka tauhohe te hauwaiwai konutai ki te wai hei whakarite i te hauwaiwai konutai me te hauwai.
Ko te konutai waikura parakore he tioata hiriwa rite ki te ngira, ko ngā hua konutai waikura e wātea ana i te hokohoko he paura tioata hina ngawari, ko te ōwehenga o te konutai waikura he 25% ki te 50% e marara ana i roto i te hinu. Ko te mātotoru whanaunga he 0.92. Ko te konutai waikura he hanganga momo tote toka (pūmau whatunga a = 0.488nm), ā, hei konutai waikura lithium i roto i te tioata ionic, kei roto te katote hauwai i te ahua anion. Ko te wera o te hanganga he 69.5kJ · mol-1, i te pāmahana teitei o te 800 ℃, ka pirau hei konutai me te hauwai whakarewa; ka pirau tere i roto i te wai; ka tauhohe kaha ki ngā waipiro iti iho; ka rewa i roto i te konutai rewa me te konutai hauwai rewa; kāore e rewa i roto i te haukini wai, te benzene, te waro tetrachloride me te waro disulfide.
He mārō hina. Ka hangaia e te hauwai konutai parakore he tioata poraka kore tae; heoi, kei roto i te hua arumoni he toenga o te konganuku konutai, ka hoatu he tae hina mārama. I te pēhanga hauātea, ka āta whanake te hauwai konutai ki runga ake i te 300 ℃. I te 420 ℃ ka tere te pirau engari kāore e puta te rewa. He tote te hauwai konutai, nō reira kāore e wairewa i roto i ngā whakarewa waro kore mahi. Ka wairewa i roto i te hauwai konutai rewa, i roto i ngā koranu konutai – pāhare pāporo me ngā ranunga LiCl – KCl rewa (352 ℃). He pumau te hauwai konutai i roto i te hau maroke engari ka mura i runga ake i te 230 ℃, ka tahuna hei hanga waikura konutai. Ka tere te waikura i roto i te hau makuku, ā, hei paura maroke ka mura noa. Ka tino kaha te tauhohenga a te hauwai konutai ki te wai, ko te wera o te waikura he nui hei mura i te hauwai kua tukuna. Ka tauhohe ki te hauhā waro hei hanga waikura konutai.
Tono
Ka taea te whakamahi i te konutai hauwai mō te tauhohenga whakapūhau me te alkylation, ā, ka taea hoki te whakamahi hei whakakorikori polymerization, hei hanga rongoā hangai, hei hanga kakara hoki i roto i te umanga kakara, hei hanga hauwai boron, hei waikura mata whakarewa, hei whakaiti, hei kaiwhakapūhau, hei whakamaroke me ngā tauhohenga Clay Johnson.
Whakamahia hei kaihoko whakatōtō, hei kaihoko alkylating me hei kaihoko whakaiti, me ētahi atu. He mea nui hei whakaiti i te matū rongoā, hinu kakara, tae, engari hei kaihoko whakamaroke, hei kaihoko alkylating, me ētahi atu.
I ngā pāmahana iti e kore e hiahiatia ngā āhuatanga whakaiti o te konutai pērā i te whakakotahitanga o ngā ketone me ngā aldehyde me ngā esters waikawa; i roto i te otinga me te konutai hauwai rewa hei whakaiti i te unahi waikura i runga i ngā konganuku; i ngā pāmahana tiketike hei kaihoko whakaiti me te whakakorikori whakaiti.
Ka whakamahia te konutai hauwai hei whakarei ake i ngā tauhohenga whakapūpū o ngā pūhui warowaihā mā te whakapūpū Dieckmann, te whakapūpū Stobbe, te whakapūpū Darzens me te whakapūpū Claisen. He matū whakaiti tēnei e whakamahia ana hei hanga diborane mai i te boron trifluoride. Ka whakamahia hoki i roto i ngā waka pūtau wahie. Hei tāpiri, ka whakamahia hei whakamaroke i ētahi whakarewa waro. Hei tāpiri atu ki tēnei, ka whai wāhi atu ki te hanga i ngā whanariki ylides, e whakamahia ana hei huri i ngā ketone ki ngā epoxides.
Te Tākai me te Rokiroki
Tākai: 100 karamu/ kēne; 500 karamu/ kēne; 1 kirokaramu mō ia kēne; 20 kirokaramu mō ia pūwero rino
Rokiroki: Ka taea te rongoa i roto i ngā kēne whakarewa me te taupoki o waho hei tiaki, i roto rānei i ngā pūwero whakarewa hei ārai i ngā kino ā-ringa. Rokirokihia ki tētahi wāhi motuhake, hauhautanga, maroke, me te hauhautanga pai, ā, kia tino ārai i te makuku. Me pai te hauhautanga o ngā whare, ā, me kore e kohikohi hau te hanganga.
