Orthoformates, raws li cov organic tebchaw muaj ob qho tib si ether thiab ester daim ntawv cog lus cov yam ntxwv, muaj kev siv dav hauv cov khoom siv hluavtaws thiab cov khoom siv. Txawm li cas los xij, lawv cov qauv molecular ua rau lawv yooj yim rau decomposition lossis deterioration thaum khaws cia vim yog ib puag ncig. Txhawm rau kom ntseeg tau tias lawv cov tshuaj lom neeg ruaj khov thiab kev siv nyab xeeb, cov khoom tshwj xeeb yuav tsum tau tsim thiab siv raws li lawv cov khoom siv physicochemical, suav nrog cov khoom xws li kev xaiv lub thawv, kev tswj hwm ib puag ncig, kev zam ntawm cov xwm txheej tsis sib xws, thiab kev tswj hwm kev nyab xeeb.
Ua ntej, orthoformates yuav tsum tau muab khaws cia rau hauv qhov zoo - kaw, corrosion- cov thawv tiv thaiv uas sib haum nrog lawv cov ntsiab lus. Muab lawv rhiab heev rau ya raws, iav los yog inert polymer fwj nrog zoo sealing zog yuav tsum tau siv, kom nruj seals kom tsis txhob ya raws ingress. Sab nraum lub thawv yuav tsum tau sau meej meej nrog cov khoom npe, batch naj npawb, concentration, phom sij profile, thiab hnub khaws cia kom yooj yim tswj thiab traceability.
Kev tswj ib puag ncig ib puag ncig yog qhov tseem ceeb rau kev ua kom ruaj khov zoo. Orthoformates yuav tsum muab cia rau hauv qhov chaw txias, qhuav, thiab zoo -ventilated warehouse. Qhov zoo tshaj plaws cia kub yog 5℃mus rau 25℃kom tsis txhob thermal decomposition los yog accelerated sab tshwm sim los ntawm kub kub. Tus txheeb ze cov av noo yuav tsum tau khaws cia qis dua 40% txhawm rau tiv thaiv hygroscopic hydrolysis thiab tsim cov methanol thiab sib xws carbonates lossis cawv. Lub teeb tseem tuaj yeem txhawb nqa isomerization lossis photolysis; Yog li ntawd, qhov chaw cia yuav tsum tau ntxoov ntxoo los yog cov orthoformates yuav tsum tau muab tso rau hauv opaque txee. Rau qis-boiling{10}} taw tes lossis volatile orthoformates, nws yog ib qho tseem ceeb tshwj xeeb los tiv thaiv vapor tsub zuj zuj hauv qhov chaw kaw; tawg- cov khoom pov thawj qhov cua yuav tsum tau siv los tswj cov cua ntws.
Hais txog cov xwm txheej tsis sib xws, orthoformates yuav tsum raug zam los ntawm kev khaws cia lossis sib cuag nrog cov acids muaj zog, muaj zog hauv paus, thiab muaj zog oxidizers. Cov tshuaj acidic lossis alkaline tuaj yeem ncaj qha catalyze lawv cov hydrolysis lossis alcoholysis cov tshuaj tiv thaiv, ua rau poob ntawm cov khoom xyaw nquag thiab muaj peev xwm tsim cov khoom tawg los yog tshuaj lom; oxidizers muaj zog tuaj yeem ua rau oxidation tshwm sim, ua rau muaj kev pheej hmoo ntawm hluav taws kub lossis tawg. Tsis tas li ntawd, qhov chaw cia khoom yuav tsum nyob deb ntawm qhov chaw tshav kub, qhib nplaim taws, thiab cov khoom siv uas yuav ua rau muaj teeb meem. Hauv pem teb yuav tsum tau xau- pov thawj, thiab cov khoom siv thaum muaj xwm ceev rau nqus thiab nruab nrab cov khoom xau yuav tsum tau yooj yim.
Kev tswj hwm kev nyab xeeb kuj tseem yog qhov tseem ceeb. Kev nkag mus rau thaj chaw khaws cia yuav tsum txwv rau cov neeg ua haujlwm tsis tau tso cai, thiab cov neeg ua haujlwm tau txais kev cob qhia yuav tsum tsis tu ncua xyuas qhov tseeb ntawm cov ntim khoom thiab sau cov ntaub ntawv ib puag ncig. Rau cov khoom khaws cia ntev- lub sij hawm, yuav tsum tsim kom muaj kev sib hloov, ua raws li "thawj-hauv, ua ntej- tawm" txoj hauv kev kom txo tau qhov tsis zoo los ntawm kev cia ntev. Yog tias pom cov ntim khoom puas lawm, cov kua xau, lossis cov ntxhiab tsw txawv txav, yuav tsum tau cais tawm tam sim ntawd thiab ntsuas kev kub ntxhov tsim nyog los tiv thaiv kev sib kis.
Hauv cov ntsiab lus, kev cia ntawm orthoformate esters yuav tsum tsom rau kev tiv thaiv cov dej noo, tiv thaiv lub teeb, tswj qhov kub thiab txias, thiab kev sib cais ntawm cov khoom tsis sib xws. Los ntawm kev tshawb fawb lub thawv thiab kev tswj cov khoom lag luam, nrog rau kev tiv thaiv kev nyab xeeb, lawv cov tshuaj lom neeg ruaj khov thiab kev siv nyab xeeb tuaj yeem ua kom ntseeg tau, muab cov khoom siv txhim khu kev qha rau kev sib txuas thiab kev ua haujlwm tom ntej.
