Vim hais tias nws yog thawj zaug pom nyob rau hauv qhuav distillation ntawm ntoo, nws kuj hu ua & ldquo; ntoo cawv & rdquo; los yog & ldquo; ntoo plig & rdquo;. Cov koob tshuaj tsawg tshaj plaws ntawm tib neeg qhov ncauj lom yog txog 100mg / kg lub cev hnyav, qhov ncauj noj ntawm 0.3 ~ 1g / kg tuaj yeem ua rau tuag taus. Siv nyob rau hauv kev tsim cov formaldehyde thiab tshuaj tua kab, thiab lwm yam., thiab siv raws li ib tug extractant ntawm organic teeb meem thiab cawv denaturant, thiab lwm yam.. Cov khoom tiav feem ntau yog tsim los ntawm reacting carbon monoxide nrog hydrogen.
Product Properties thiab Stability:
Cov kua tsis muaj xim tsis muaj xim, nws cov vapor thiab cua tuaj yeem tsim cov khoom tawg, thaum kub hnyiab los tsim cov nplaim xiav. Qhov ntsuas kub tseem ceeb 240.0 ° C; Lub siab tseem ceeb 78.5atm, miscible nrog dej, ethanol, ether, benzene, ketones thiab lwm yam organic solvents. Nws cov vapors ua rau tawg sib xyaw nrog huab cua, uas tuaj yeem ua rau combustion thiab tawg thaum raug qhib hluav taws thiab kub kub. Nws tuaj yeem cuam tshuam nrog oxidant. Yog tias nws ua tau raws li qhov kub kub, qhov siab hauv lub thawv nce, thiab muaj kev txaus ntshai ntawm kev tawg thiab tawg. Tsis muaj nplaim taws thaum hlawv. Nws tuaj yeem tsim hluav taws xob zoo li qub thiab ignite nws vapor.
Khoom siv:
1.Ib qho ntawm cov khoom siv organic yooj yim, siv hauv kev tsim cov chloromethane, methylamine thiab dimethyl sulphate thiab ntau lwm cov khoom organic. Nws tseem yog cov khoom siv raw rau cov tshuaj tua kab (secticides, acaricides), tshuaj (sulfonamides, hapten, thiab lwm yam), thiab ib qho ntawm cov khoom siv raw rau kev sib txuas ntawm dimethyl terephthalate, methyl methacrylate thiab methyl acrylate.
2.Qhov kev thov tseem ceeb ntawm methanol yog kev tsim cov formaldehyde.
3.Ib qho tseem ceeb ntawm kev siv methanol yog kev tsim cov acetic acid. Nws tuaj yeem tsim cov yas acetate, acetate fiber ntau thiab acetate, thiab lwm yam. Nws qhov kev thov yog ze ze rau cov xim, nplaum thiab textiles.
4.Methanol tuaj yeem siv los tsim methyl formate.
5.Methanol tseem tuaj yeem tsim cov methylamine, methylamine yog ib qho tseem ceeb fatty amine, nrog kua nitrogen thiab methanol ua raw cov ntaub ntawv, tuaj yeem txiav txim siab los ntawm kev ua cov methylamine, dimethylamine, trimethylamine, yog ib qho ntawm cov khoom siv tshuaj lom neeg yooj yim.
6.Nws tuaj yeem ua ke rau hauv dimethyl carbonate, uas yog cov khoom lag luam zoo ib puag ncig thiab siv hauv tshuaj, kev ua liaj ua teb thiab kev lag luam tshwj xeeb, thiab lwm yam.
7.Nws tuaj yeem ua ke rau hauv ethylene glycol, uas yog ib qho ntawm petrochemical intermediate raw cov ntaub ntawv thiab tuaj yeem siv rau hauv kev tsim cov polyester thiab antifreeze.
8.Nws tuaj yeem siv rau hauv kev tsim cov khoom txhawb kev loj hlob, uas yog qhov zoo rau kev loj hlob ntawm cov qoob loo qhuav.
9.Kuj kuj tuaj yeem ua ke ntawm methanol protein, methanol li raw khoom tsim los ntawm microbial fermentation ntawm methanol protein yog lub npe hu ua tiam thib ob ntawm ib leeg-cell proteins, compa ualiab nrog ntuj proteins, khoom noj muaj txiaj ntsig yog siab dua, cov ntsiab lus ntawm cov nqaij nyoos yog ntau dua li cov nqaij ntses thiab cov taum pauv, thiab muaj cov amino acids, minerals thiab vitamins, uas tuaj yeem siv rau hauv qhov chaw ntawm ntses, taum, pob txha noj mov. , nqaij thiab skimmed mis nyuj hmoov.
10.Methanol yog siv los ntxuav thiab degreasing tus neeg sawv cev.
11.Siv raws li kev tshuaj ntsuam reagent, xws li cov kuab tshuaj, cov tshuaj methylation reagents, chromatographic reagents. Kuj tseem siv rau hauv cov organic synthesis.
12. Feem ntau methanol yog cov kuab tshuaj zoo dua li ethanol, tuaj yeem yaj ntau cov ntsev inorganic. Tseem tuaj yeem muab sib xyaw rau hauv roj av ua lwm yam roj. Methanol yog siv nyob rau hauv zus tau tej cov roj av octane additive methyl tertiary butyl ether, methanol roj av, methanol roj, thiab methanol protein thiab lwm yam khoom.
13.Methanol tsis yog tsuas yog ib qho tseem ceeb ntawm cov khoom siv raw, tab sis kuj yog lub zog thiab lub tsheb roj nrog kev ua haujlwm zoo heev. Methanol reacts nrog isobutylene kom tau MTBE (methyl tertiary butyl ether), uas yog ib tug high-octane unleaded roj av additive thiab kuj yuav siv tau raws li ib tug hnyav. Tsis tas li ntawd, nws tseem tuaj yeem siv los tsim cov olefins thiab propylene.
14.Methanol tuaj yeem siv los tsim dimethyl ether. Cov kua roj tshiab ua los ntawm methanol thiab dimethyl ether formulated nyob rau hauv ib qho kev faib ua feem hu ua cawv ether roj. Nws combustion efficiency thiab thermal efficiency yog siab tshaj liquefied roj.
Cov ntawv khaws cia khoom:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov.
3. Khaws lub thawv kaw.
4.Nws yuav tsum tau muab cais tawm ntawm dej, ethanol, ether, benzene, ketones, thiab yuav tsum tsis txhob sib xyaw.
5. Txwv tsis pub siv cov cuab yeej siv tshuab thiab cov cuab yeej uas yooj yim los tsim cov pob zeb.
Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
