Hoʻohana pinepine ʻia lākou no ka hoʻopili ʻana i ka pauka.Pili ia i nā koi o nā mea kūʻai aku.No laila, e haʻi mai iā mākou i kāu koi ma mua o ka hoʻopaʻa ʻana inā loaʻa iā ʻoe nā noi kūikawā.
1kg a 25kg He paʻakikī ka paʻi waho.A he mea paʻakikī ke ʻoki a hōʻino.Hiki iā ia ke pale pono i kāu mau huahana.
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 momona momona 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.

1. No ka MOQ: Hiki iā mākou ke hoʻololi e like me kāu koi.
2. E pili ana i ka hāpana: Pono ka hāpana i ka uku hōʻailona, hiki ke lawe i ka ukana e hōʻiliʻili aiʻole hiki iāʻoe ke uku iā mākou ma mua.
3. Mold workshop, hiki ke hoʻopilikino ʻia e like me ka helu o nā hiʻohiʻona.
4. Hāʻawi mākou i ka lawelawe maikaʻi loa.Ke hana nei kekahi hui kūʻai akamai iā ʻoe.
5. E pili ana i ka hoʻololi: E ʻoluʻolu e leka uila a kamaʻilio mai iaʻu ma kou ʻoluʻolu.
