Methanol a meisopropanolʻelua mau mea hoʻoheheʻe hana maʻamau.ʻOiai kaʻana like lākou, loaʻa iā lākou nā ʻano ʻokoʻa a me nā hiʻohiʻona e hoʻokaʻawale iā lākou.Ma kēia ʻatikala, e ʻimi mākou i nā kikoʻī o kēia mau solvents ʻelua, ka hoʻohālikelike ʻana i kā lākou mau waiwai kino a me nā kemika, a me kā lākou noi a me nā ʻaoʻao palekana.

E hoʻomaka kākou me ka methanol, i ʻike ʻia hoʻi he ʻawaʻawa lāʻau.He wai akaka, waihoʻoluʻu ʻole i hui pū ʻia me ka wai.He wahi paila haʻahaʻa ko ka Methanol he 65 degere Celsius, he mea kūpono ia no ka hoʻohana ʻana i nā noi haʻahaʻa haʻahaʻa.Loaʻa iā ia ka helu octane kiʻekiʻe, ʻo ia ka mea hiki ke hoʻohana ʻia e like me ka solvent a me ka anti-knock agent i ka ʻaila.

Hoʻohana pū ʻia ka Methanol ma ke ʻano he meaʻai i ka hana ʻana i nā kemika ʻē aʻe, e like me formaldehyde a me dimethyl ether.Hoʻohana pū ʻia ia i ka hana ʻana i ka biodiesel, kahi kumu wahie hou.Ma waho aʻe o kāna mau hana ʻoihana, hoʻohana pū ʻia ka methanol i ka hana ʻana i nā varnish a me nā lacquers.

I kēia manawa, e huli kākou i ka isopropanol, i ʻike ʻia ʻo 2-propanol a i ʻole dimethyl ether.He akaka a kala ʻole kēia mea hoʻoheheʻe, ʻoi aku ka kiʻekiʻe o ka paila ma mua o ka methanol ma 82 degere Celsius.Hiki i ka Isopropanol ke hui pū me ka wai a me nā lipids, e lilo ia i mea hoʻoheheʻe maikaʻi loa no ka nui o nā noi.Hoʻohana mau ʻia ʻo ia ma ke ʻano he mea ʻokiʻoki i nā mea ʻokiʻoki pena a i ka hana ʻana i nā mīkina lima latex.Hoʻohana ʻia ʻo Isopropanol i ka hana ʻana i nā mea hoʻopili, sealants, a me nā polymers ʻē aʻe.

I ka wā e pili ana i ka palekana, loaʻa i ka methanol a me ka isopropanol ko lākou mau pōʻino kūʻokoʻa.He mea ʻawaʻawa ka Methanol a hiki ke hoʻopōpoʻo inā paʻi ʻia i nā maka a i ʻai ʻia paha.He hikiwawe loa ia a pahū ke hui me ka ea.Ma ka ʻaoʻao ʻē aʻe, ʻoi aku ka haʻahaʻa o ka isopropanol a ʻoi aku ka liʻiliʻi o ka pahū ma mua o ka methanol ke hui pū me ka ea.Eia nō naʻe, hiki ke hoʻopau ʻia a pono e mālama pono ʻia.

I ka hopena, ʻo ka methanol a me ka isopropanol nā mea hoʻoheheʻe ʻoihana waiwai me kā lākou mau waiwai ponoʻī a me nā noi.ʻO ka koho ma waena o lākou e pili ana i nā koi kūikawā o ka noi a me ka ʻike palekana o kēlā me kēia solvent.He haʻahaʻa ko ka Methanol a ʻoi aku ka pahū, ʻoiai ʻo ka isopropanol he ʻoi aku ka nui o ka paila a ʻoi aku ka liʻiliʻi o ka pahū akā hiki ke lapalapa.Ke koho ʻana i kahi mea hoʻoheheʻe, pono e noʻonoʻo i kona mau waiwai kino, kūpaʻa kemika, ʻona, a me ka ʻike flammability e hōʻoia i ka palekana a me ka hoʻohana pono.
