Ua ʻike nui ʻia kā mākou mau hoʻonā a hilinaʻi ʻia e nā mea hoʻohana a hiki ke hoʻokō mau i nā koi hoʻokele waiwai a me ka nohona no Kina. ʻO ke kumu kūʻai haʻahaʻa ʻo Chuangyu Chemical Sodium Ethanolate CAS 141-52-6, Loaʻa nā waiwai āpau me ke kūlana kiʻekiʻe a me nā huahana a me nā lawelawe ma hope o ke kūʻai aku. ʻO ka mākeke a me ka mea kūʻai aku ka mea a mākou e ʻimi nei. Ke manaʻo nui nei i ka laulima Win-Win!
Ua ʻae nui ʻia kā mākou mau hoʻonā a hilinaʻi ʻia e nā mea hoʻohana a hiki ke hoʻokō i nā koi waiwai a me nā pono kaiāulu e ulu mau nei noKina Sodium Ethoxide a me ka wai Sodium Ethoxide, Ma hope o 13 mau makahiki o ka noiʻi ʻana a me ka hoʻomohala ʻana i nā huahana, hiki i kā mākou hōʻailona ke hōʻike i nā ʻano huahana a me nā hoʻonā me ka maikaʻi loa ma ka mākeke honua. Ua hoʻopau mākou i nā ʻaelike nui mai nā ʻāina he nui e like me Kelemānia, ʻIseraʻela, Ukraine, United Kingdom, Italia, Argentina, Farani, Brazil, a pēlā aku. Manaʻo paha ʻoe ua palekana a māʻona hoʻi i ka wā e launa pū ai me mākou.

ʻAno kemika

Pauka keʻokeʻo a melemele paha; hygroscopic; ʻeleʻele a palaho i ka wā e ʻike ʻia ai i ka lewa; palaho i ka wai e hana ana i ka sodium hydroxide a me ka ethanol; hoʻoheheʻe ʻia i loko o ka ethanol loa. Hana ikaika me nā waikawa, ka wai. Kūlike ʻole me nā mea hoʻoheheʻe chlorinated, ka makū. Hoʻopili i ke kalapona dioxide mai ka lewa. Hiki ke lapalapa.

Nā noi

Hoʻohana ʻia ka sodium ethoxide i ka hana organik no nā hopena condensation. He mea hoʻouluulu nō hoʻi ia i nā hopena organik he nui.

ʻO ka sodium ethoxide, 21% w/w i loko o ka ethanol, hoʻohana ʻia ia ma ke ʻano he kumu ikaika i ka synthesis organik. Loaʻa iā ia ka hoʻohana ʻana i nā ʻano kemika like ʻole e like me ka condensation, esterification, alkoxylation a me ka etherifcation. Ke komo ikaika nei ia i ka Claisen condensation, ka Stobbe reaction a me ka Wolf-kishner reduction. He mea hoʻomaka koʻikoʻi ia no ka synthesis o ka ethyl ester a me ka diethyl ester o ka malonic acid. I ka Williamson ether synthesis, hana ia me ka ethyl bromide e hana i ka diethyl ether.

Ola papa

Wahi a ko mākou ʻike, hiki ke mālama ʻia ka huahana no 12 mau mahina mai ka lā i lawe ʻia ai inā mālama ʻia i loko o nā pahu i hoʻopaʻa pono ʻia, pale ʻia mai ka mālamalama a me ka wela a mālama ʻia ma nā mahana ma waena o 5 - 30°C.
