Triethyl orthoformateTriethyl orthoformate / 99% TEOF CAS 122-51-0
Triethyl orthoformate (TEO/TEOF), imusanganiswa we orthoester, wakarongwa se ester, fomura yawo yemamorekuru iHC(OC2H5)3. Triethyl orthoformate imvura yakajeka, isina ruvara ine hwema hunorwadza. Inonyungudika zvishoma mumvura uye inogona kuora mumvura; inogona kusanganiswa ne ethanol ne ether. Haina chepfu yakawanda. Kazhinji, Triethyl orthoformate (TEOF) inoshandiswa se pharmaceutical intermediate (API) munzvimbo dzekurapa, dzakadai sekugadzira mishonga yekurwisa malaria chloroquine ne quinpir. Inoshandiswawo sezvinhu zvekugadzira mifananidzo uye se reagent mukugadzirwa kweBodroux-Chichibabin aldehyde.
TEOF inoshandiswa semushonga wekusimbisa machira epolyurethane. Inoshanda neisocyanate nepolyester. Inoshandiswa semushonga wekubvisa hunyoro mumachira eisocyanate nepolyester. Miedzo inofanira kuitwa nguva dzose kuti ione kana chigadzirwa chacho chakakodzera kushandiswa kwacho. Kazhinji, TEOF inoshandiswa zvakanyanya pasilicon, pendi, sealants, sprays nezvimwewo. Kunze kweizvozvo, TEOF inogonawo kushandiswa kugadzira zvinhu zvinosanganisa makemikari (intermediates) uye API (Active Pharmaceutical Ingredients) mukurapa.
Pakeji Yechigadzirwa: Drum yepurasitiki kana dram yesimbi yakarungwa, huremu hwayo hwe180kgs padram imwe neimwe kana zvichienderana nezvinodiwa nevatengi.
Kuchengetera Chigadzirwa: Isa munzvimbo yakavharwa, yakaoma uye ine mhepo inofefetera, Dzivirira Moto.
Triethyl orthoformate (TEO/TEOF) chinhu chakakosha chekugadzirwa kwemakemikari. Inonyanya kushandiswa kugadzira mishonga nemishonga yezvipembenene, zvakaita sequinolones antibiotics neAmitraz. Inoshandiswawo zvakanyanya mumaindasitiri ekuputira, kudhaya nezvinonhuwira. Pamusoro pezvo, TEOF inoshandiswa semushonga wekubvisa hunyoro mumasystem ekuputira eisocyanate nepolyester.
