N, N-Diethylaniline CAS:91-66-7
ʻO N, N-diethylaniline he waiʻaila melemele māmā i hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā dyes azo, triphenylmethane dyes, a me nā mea ʻē aʻe.
ala synthetic
E hoʻopau i ka dppe (1 mg, 0.0025 mmol) i loko o ka nBu2O maloʻo (1 mL) a hoʻohui i ka Karstedt catalyst (29 μL, 0.0025 mol) i loko o kahi paipu Schlenk ma lalo o ka lewa argon. Ma hope o ka hoʻoulu ʻana i ka hui no 10 mau minuke, ua hoʻohui ʻia ka PhSiH3 (247 μL, 2.0 mmol). Aniline (45.6 μL, 0.5 mmol), n-hexadecane (50 μL) e like me ka maʻamau kūloko, a me CH3ChemicalbookCO2H (63 μL, 1.1 mmol) ua hoʻohui koke ʻia, a laila hoʻoulu ʻia i ka lumi wela no 18 mau hola. I ka pau ʻana, ua hoʻoheheʻe ʻia ka hui ʻana me ka ethyl acetate (15 mL), hoʻopau pono ʻia me ka wai NaOH (3M solution; 5 mL), a hoʻoulu ʻia ma ka lumi wela no 3 mau hola. Ua unuhi ʻia ka hui ʻana me ka ethyl acetate (ʻekolu manawa), a ua maloʻo nā ʻāpana organik i hui ʻia ma luna o MgSO4 anhydrous. Ua kānana ʻia, hoʻopaʻa ʻia, a hoʻomaʻemaʻe ʻia e ka silica gel column chromatography (n-hexane/ethyl acetate mixture) e hāʻawi iā N,N-diethylaniline.

ʻIkepili Hui
ʻO MIT-IVY INDUSTRY CO., LTD he mea hana a me ka mea hoʻopuka i nā mea pena kemika maikaʻi a me nā mea waena lāʻau lapaʻau ma Kina.
Hana nui i nā huahana aniline a me nā huahana chlorine series.
MIT –IVY Chemicals Industry Co., Ltd. He mea hana nui ia no 21 mau makahiki me nā lako hana piha a me ka mālama pono a me ka mālama ʻana i nā mīkini.
Hoʻohana mākou i ka ʻenehana hana kiʻekiʻe a me nā ʻano hoʻāʻo e ʻike ai i ka hana, ka hoʻomalu ʻana i ka maikaʻi e hoʻokō i ka maʻamau. Ua ʻae ʻia mākou e SGS, ISO9001, ISO140 01, GB/HS16949 a me T28001.
ʻO nā huahana nui ʻo Mit-Ivy e like me kēia:
API, nā lāʻau lapaʻau waena, Dye intermediates, maikaʻi, nā kemika kūikawā, Waterborne industry pena a me nā mea ikehu hou.
ʻO kā mākou mau mākeke nui ʻo ʻAmelika, India, ʻApelika, Indonesia, Turkey, Hema-hikina Asia, West Asia a pēlā aku. ʻO MIT-IVY Industry ʻO nā huahana nui kaʻana i ka 97% o ka mākeke kūloko kūikawā i ka hana a me ka hoʻokele, hiki iā mākou ke hoʻolako i nā huahana me ka uku hoʻokūkū. me ka maikaʻi maikaʻi a me ke kumukūʻai a hoʻokipa ʻia e kūkākūkā. Loaʻa i kā mākou ʻoihana nā poʻe loea i mea nui i ka R&D chemical a me ka hoʻokele sicentific, hoʻolako i nā huahana kemika maikaʻi me ke kūlana kiʻekiʻe a me ka lawelawe kokoke, hoʻolako pū i nā huahana kuʻuna e like me ka koi o kā mākou mea kūʻai aku. Loaʻa iā mākou kahi hui hana hoʻokele maikaʻi a hoʻoikaika iā mākou iho me kahi kuʻuna maʻamau, mālama a me ka hoʻokō ma o ka hui pū ʻana, hoʻoikaika kā mākou hui e hoʻokō i ka kūleʻa i ka leʻaleʻa i kā mākou mea kūʻai aku a iā mākou iho. Ke hoʻomau nei mākou i kā mākou huahana a hoʻomaikaʻi i kā mākou lawelawe, ʻoihana kūʻai. No laila, hoʻomaka mākou i ke ʻano kūʻai mua ma ka ʻupena ma Kina, ʻo ia ke kālepa kūʻai o nā pūʻolo liʻiliʻi e lawe pū mai i nā ʻano hoʻokele like ʻole. Hoʻolaha nui ʻia kā mākou huahana i South Korea, Vietnam, Australia, ʻEulopa a me ʻAmelika Hema, i manaʻo nui ʻia e kā mākou mea kūʻai. Ke koi nei mākou i ka manaʻo hoʻokele "ʻO ka mākeke ko mākou panana, ʻo ka maikaʻi ko mākou ola, ʻo ke kālā ko mākou ʻuhane". ʻO ka hilinaʻi o nā mea kūʻai aku ʻo kā mākou pauka i mua, ʻo kā lākou ʻoluʻolu ʻo kā mākou pahuhopu hakakā.
Ka lawelawe mea kūʻai mai Brand:
Hoʻokumu a hoʻokō kā mākou hui pūʻulu moʻokāki JIT mea kūʻai aku ma Kina i nā manaʻo i hana ʻia no ka hoʻolako maikaʻi ʻana o kā mākou mea kūʻai aku me nā kemika ʻoihana a me nā mea kūikawā.
ʻO kāu mau mea maikaʻi:
● Kākoʻo ka lawelawe lawelawe kikowaena kikowaena i ka maʻalahi o nā kaʻina hana hoʻokele, ka hopena i ka manawa a me ke kumu kūʻai.
