No nā nīnau e pili ana i kā mākou huahana a i ʻole ka papa inoa kumukūʻai, e ʻoluʻolu e waiho i kāu leka uila iā mākou a e hoʻopili mākou i loko o 24 mau hola.
NINAU ANOʻO ke kūlana kaʻaahi a me ke ʻano hoʻouna i ʻōlelo ʻia:
Ma ka lewa, ma ke kai a ma ke ala pololei
Kūlana mālama:
E mālama ma kahi pouli, Hoʻopaʻa ʻia i kahi maloʻo, Ke ana wela o ka lumi
Ka helu kauoha liʻiliʻi:
Kūkākūkā
palapala hōʻoia:
COA, HPLC, GC, HNMR, Assay, Water Content(KF), TLC loaʻa
Hoʻohana mau ʻia lākou no ka ʻeke pauda.A hiki iā lākou ke pale i ka lā a me ka wai mai ka pōʻino.
Hiki i ka pahu paʻakikī ke pale i kāu huahana mai ka hāʻule a pulu.
Hana ʻia ʻo Ester mai ka hopena esterization o ka waika inorganic a i ʻole ka waikawa organik a i ʻole ka waiʻona.Hiki i ka waiʻona a i ʻole phenol a i ʻole acidic anhydride, ka waiʻona a me ka ethylene, ka ʻakika ʻakika manuahi a me nā derivatives fatty nitrogen hiki ke hoʻohua i ka ester.ʻO ka hydrogen ma ka alpha-carbon i loko o nā molekala ester e nalowale i ka waiʻona molekala me kahi ester molekala ʻē aʻe ma lalo o nā kūlana alkaline e hoʻohua ai i ka ester β-keto, i kapa ʻia ʻo ester contraction reaction.No ka laʻana, hana ʻia ka acetyl acetate e hana i ka acetyl ethyl acetate.He mea koʻikoʻi kēia pane i ka synthesis organik.
ʻO ka inoa o ka ester mai ka inoa like o ka waikawa carboxylic a me ka waiʻona a i ʻole phenol, e like me "kahi waikawa a me kekahi ester".Ua kapa ʻia nā esters pōʻai he lactone (lactone).ʻO nā waiwai kemika o ka ester ua like ia me ka amyl niche anhydride, ka mea maʻalahi i ka hydrolysis, ka waiʻona a me ka hopena amonia.ʻO ka ester haʻahaʻa haʻahaʻa he wai ʻala a me ka ʻole o ka waihoʻoluʻu, a paʻa ka ester kiʻekiʻe.ʻO Estes nā mea hoʻoheheʻe koʻikoʻi a me nā mea waiwai synthetic, a ʻo kekahi mau esters he lāʻau lapaʻau ponoʻī.E like me ke ʻano o ka waika, hiki ke hoʻokaʻawale ʻia ka ester i ka ester acid inorganic a me ka ester acid organic.ʻO Etate, he ester momona ka ethyl acetate, he ester aromatic ka acetate, a he ester cyclic ka namanonate.
