Triethyl orthoformateTriethyl orthoformate / 99% TEOF CAS 122-51-0
ʻO Triethyl orthoformate (TEO/TEOF), he pūhui orthoester, i hoʻokaʻawale ʻia ma ke ʻano he ester, ʻo kona ʻano molekala ʻo HC(OC2H5)3. ʻO Triethyl orthoformate he wai maʻemaʻe, kala ʻole me ka ʻala ʻala. Hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i ka wai; hiki ke hui me ka ethanol a me ka etera. Haʻahaʻa ʻona. ʻO ka maʻamau, hoʻohana ʻia ʻo Triethyl orthoformate (TEOF) ma ke ʻano he pharmaceutical intermediate (API) i nā wahi olakino, e like me ka hoʻomākaukau ʻana i nā lāʻau antimalarial chloroquine a me quinpir. Hoʻohana ʻia ia ma ke ʻano he mea maka no nā mea paʻi kiʻi a ma ke ʻano he reagent i ka synthesis o Bodroux-Chichibabin aldehyde.
Hoʻohana ʻia ʻo TEOF ma ke ʻano he stabilizer no nā uhi polyurethane. He kūpono ia me ka isocyanate a me ka polyester. ʻO ka lilo ʻana i mea hoʻomaʻemaʻe i ka ʻōnaehana isocyanate a me ka polyester coating. Pono e hoʻokō mau ʻia nā hoʻokolohua e hoʻoholo ai i ke kūpono o ka huahana no ka noi i manaʻo ʻia. ʻO ka mea maʻamau, hoʻohana nui ʻia ʻo TEOF ma ke silika, pena, sealants, sprays a pēlā aku.
Pākuʻi Huahana: ʻO ka pahu pahu a i ʻole ka pahu hao galvanized, ʻupena paona 180kgs no ka pahu a i ʻole e like me nā koi o nā mea kūʻai.
Waihona Huahana: E hookomo i kahi i sila, maloo a me ka ea, Kiai i ke ahi.
ʻO Triethyl orthoformate (TEO/TEOF) kahi mea koʻikoʻi o ka synthesis organik. Hoʻohana nui ʻia ia e synthesize i nā huahana lāʻau a me nā pesticide, e like me nā quinolones antibiotic a me Amitraz. Hoʻohana nui ʻia ia i ka uhi ʻana, ka wai a me nā ʻoihana ʻala. Eia kekahi, hoʻohana ʻia ʻo TEOF ma ke ʻano he scavenger moisture i ka isocyanate a me ka polyester coating system.
