Hoʻolauna

waiwai kemika

ʻO ka wai ʻālohilohi ʻole me ka ʻala aldehyde asphyxiating. Hiki ke hoʻoheheʻe ʻia i ka wai. Miscible me ka ethanol, ether, ethyl acetate, acetone, toluene, nā ʻano mea hoʻoheheʻe a me nā aila ʻē aʻe.

Hoʻohana

Hoʻohana ʻia i ka synthesis organik a me kahi mea maka no ka hana ʻana i nā mea ʻala

Hoʻohana

Hōʻike ʻo GB 2760-96 i nā mea ʻala hiki ke ʻae ʻia e hoʻohana. Hoʻohana nui ʻia e hoʻomākaukau i ka maiʻa, caramel a me nā mea ʻono hua ʻē aʻe.

Hoʻohana

ʻO butyraldehyde kahi mea waena koʻikoʻi. Hiki ke hana 'ia ka n-butanol e ka hydrogenation o n-butanal; Hiki ke hana ʻia ka 2-ethylhexanol e ka condensation dehydration a laila hydrogenation, a ʻo n-butanol a me 2-ethylhexanol ka mea nui o ka plasticizers. Hiki ke hana 'ia ka n-butyric acid ma o ka oxidation o n-butyric acid; Hiki ke hana ʻia ka trimethylolpropane e ka condensation me formaldehyde, he plasticizer no ka synthesis o ka resin alkyd a me kahi mea maka no ka aila maloʻo ea; condensation me phenol e hana ai i ka resin hiki ke hoʻoheheʻe ʻia; ʻO ka condensation me ka urea hiki ke hana i ka resin hiki ke hoʻoheheʻe i ka waiʻona; ʻO nā huahana condensed me ka polyvinyl alcohol, butylamine, thiourea, diphenylguanidine a i ʻole methyl carbamate he mau mea maka a, hoʻohana ʻia ka condensation me nā ʻano ʻona like ʻole e like me ka solvent no celluloid, resin, rubber a me nā huahana lāʻau; hoʻohana ʻia ka ʻoihana lāʻau lapaʻau e hana i ka "Mianerton", "pyrimethamine", a me ka amylamide.

Hoʻohana

ʻO ke kāpili Rubber, ka mea hoʻoheheʻe pahu, ka ester resin synthetic, ka hana ʻana i ka waikawa butyric, a me nā mea ʻē aʻe. Hoʻohana ʻia e like me ka solvent no nā lipids, hoʻohana ʻia hoʻi i ka hoʻomākaukau ʻana i nā mea ʻono a me nā mea ʻala a me ka preservative.

Hana hana

I kēia manawa, hoʻohana nā ʻano hana o ka butyraldehyde i kēia mau ʻano: 1. propylene carbonyl synthesis method propylene a me ka synthesis gas e hana i ka carbonyl synthesis reaction i mua o ka Co or Rh catalyst e hoʻohua i ka n-butyraldehyde a me ka isobutyraldehyde. Ma muli o nā catalysts like ʻole a me nā kūlana kaʻina i hoʻohana ʻia, hiki ke hoʻokaʻawale ʻia i ka carbonyl synthesis kiʻekiʻe me ka cobalt carbonyl e like me ka catalyst a me ka haʻahaʻa haʻahaʻa carbonyl synthesis me ka rhodium carbonyl phosphine complex e like me ka catalyst. ʻO ke ala kaomi kiʻekiʻe he kiʻekiʻe ka hopena hopena a me nā huahana he nui, pēlā e hoʻonui ai i ke kumukūʻai hana. ʻO ke ala haʻahaʻa carbonyl synthesis haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ka lākiō isomer maikaʻi o 8-10: 1, nā huahana liʻiliʻi, kiʻekiʻe o ka hoʻololi ʻana, haʻahaʻa haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa mana, mea maʻalahi, kaʻina pōkole, e hōʻike ana i nā hopena waiwai maikaʻi a me ulu wikiwiki. 2. Acetaldehyde condensation ala. 3. Butanol oxidative dehydrogenation ala hoʻohana kala e like me ka catalyst, a butanol ua oxidized e ka ea i hoʻokahi kapuaʻi, a laila na reactants condensed, kaawale, a rectified e loaa ka huahana pau.

Hana hana

Loaʻa ia ma ka distillation maloʻo o ka calcium butyrate a me ka calcium formate.

Loaʻa ka mahu ma ka dehydrogenation o ka catalyst.
