| Tetramethylammonium chloride Siv Thiab Synthesis |
| Catalyst ntawm Organic synthesis | Tetramethylammonium chloride yog theem hloov pauv catalyst nyob rau hauv cov organic synthesis theem nrog nws cov catalytic kev ua kom muaj zog tshaj triphenylphosphine thiab triethylamine. Nyob rau hauv chav tsev kub, nws yog ib tug dawb crystalline hmoov, thiab yog volatile, irritant, thiab yooj yim rau nqus noo noo. Nws yooj yim soluble hauv methanol, soluble hauv dej thiab kub ethanol tab sis insoluble hauv ether thiab chloroform. Ua kom kub siab tshaj 230 degree ua rau nws decomposition rau trimethylamine thiab methyl chloride. Medium lethal koob tshuaj (nas, intraperitoneal) yog nyob ib ncig ntawm 25mg / kg. Nws kuj yog siv rau cov synthesis ntawm cov kua siv lead ua epoxy compound, thiab Pope thiab polarographic tsom xam, nrog rau kev lag luam hluav taws xob. Cov ntaub ntawv saum toj no yog kho los ntawm chemicalbook ntawm Dai Xiongfeng. |
| Electrolytic npaj ntawm tetramethylammonium hydroxide | Tetramethylammonium hydroxide yog ib hom organic puag, thiab muaj ntau yam kev siv hauv kev lag luam thiab kev tshawb fawb tshawb fawb. Nyob rau hauv peb lub teb chaws, nws yog tsuas yog siv raws li lub catalyst nyob rau hauv synthesis ntawm organic silicon khoom, xws li hluavtaws silicone roj, silicone roj hmab, thiab silicone resin. Txawm hais tias nws muaj qhov siv tsawg, tab sis nws tuaj yeem cuam tshuam rau ob qho tib si tawm los thiab qhov zoo ntawm cov khoom. Nyob rau hauv txawv teb chaws, nws yog tsuas yog siv rau polyester-raws li polymers, textiles, plastics, zaub mov, tawv, ntoo ua, electroplating, thiab tej yam kab mob. Tam sim no tetramethylammonium hydroxide tau nkag mus rau hauv cov chaw thev naus laus zis. Piv txwv li, nyob rau hauv kev lag luam kev lag luam ntawm hluav taws xob Circuit Court thiab microscopic nplooj ntawv ntau lawm, nws tuaj yeem siv los ua tus neeg saib xyuas kev sib koom ua ke ntawm pawg thawj coj saib xyuas thiab cov anisotropic corrosive agents ntawm Si-SiO2 interface hauv semiconductor microfabrication txheej txheem. Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, cov kev xav tau ntawm cov tshuaj no kuj tseem nce ntxiv, ua rau muaj kev xav tau ntau dua rau ob qho tib si zoo thiab kom muaj nuj nqis ntawm tetramethylammonium hydroxide. Lub hauv paus ntsiab lus ntawm kev siv cov txheej txheem electrolytic rau kev npaj ntawm tetramethylammonium hydroxide yog tias cov tshuaj aqueous ntawm tetramethylammonium chloride nyob rau hauv lub anode compartment ntawm lub electrolytic da dej, nyob rau hauv qhov kev txiav txim ntawm hluav taws xob quab yuam, muaj nws cov chloride ions migrate rau cov kev taw qhia ntawm anode mus txog rau thaum tso tawm. anode tshwm sim los tsim cov tshuaj chlorine. Meanwhile, vim yog xaiv permeability ntawm ion-pauv daim nyias nyias, chloride tsis tuaj yeem nkag mus los ntawm ion-pauv daim nyias nyias los ntawm diffusion. Hloov chaw, tsuas yog tetramethylammonium ions tuaj yeem xaiv nkag mus rau hauv cathode compartment los ntawm, thiab ua kom muaj txiaj ntsig nyob ntawd. Cov dej molecule hauv electrolyzer cathode chamber yog decomposed rau hauv hydrogen thiab hydroxyl ions. Lub tom kawg yog khi rau tetramethylammonium ions tsiv teb tsaws los ntawm lub anode chamber los tsim tetramethylammonium hydroxide. Nrog rau qhov nce ntawm hluav taws xob, tetramethylammonium hydroxide concentration txuas ntxiv txhim kho, thaum kawg ua tiav qhov xav tau kawg ntawm cov roj av. Cov tshuaj tiv thaiv anodic electrochemical yog: (CH3) 4NCL → (CH3) 4N ++ Clˉ2Clˉ-2e → Cl2 ↑ Cov tshuaj tiv thaiv cathodic electrochemical yog: H2O → H + + OHˉ (CH3) 4N ++ OHˉ → (CH3) 4NOH 2H ++ 2e → H2 ↑ Tag nrho cov tshuaj tiv thaiv yog: 2 (CH3) 4NCl + 2H2O → 2 (CH3) 4NOH + H2 ↑ + Cl2 ↑ Cov hydrogen generated thaum lub sij hawm electrolysis yog vented nrog lub resulting chlorine absorbed los ntawm alkaline tov los tsim sodium hypochlorite uas yog ib tug tseem ceeb raw cov ntaub ntawv rau ua bleach. Yog li ntawd, txoj kev no ntawm kev tsim tetramethylammonium hydroxide yog yooj yim nrog siab purity thiab ua rau tsis muaj kuab paug ib puag ncig. |
| Kev npaj ntawm PHBHQ hom thermoset kua crystalline epoxy resin (LCER) | Siv toluene ua cov kuab tshuaj, concentrated sulfuric acid thiab boric acid raws li catalyst, ntxiv rau hauv peb-caj dab ntawm qhov sib npaug ntawm hydroxybenzoic acid thiab 1,4-hydroquinone, muaj cov tshuaj tiv thaiv ntawm 120 ~ 130 degree rau 6 h; Tom qab txias, rov ntxuav dua nrog dej distilled, thiab tau txais p-hydroxybenzoic acid p-hydroquinone ester tom qab lub tshuab nqus tsev qhuav (dawb khoom, yield 87.5%). Dissolve cov khoom saum toj no nyob rau hauv ntau tshaj ntawm epichlorohydrin, ntxiv tetramethylammonium chloride thiab muaj cov tshuaj tiv thaiv ntawm 60 ~ 70 degree rau 10 h; Ntxiv kev poob siab ntawm cov dej ntau dhau ntawm 45% NaOH tov (qhov sib ntxiv yuav siv sij hawm 6 h). Ntau npaum li cas epichlorohydrin tau distilled nyob rau hauv lub siab txo; ntxuav cov tshuaj tiv thaiv nrog acetone-methanol tov tov rau crystallization; Nws yog ntxiv rau lub tshuab nqus tsev kom qhuav kom tau txais PHBHQ-hom thermosetting kua crystalline epoxy resin (nrog cov yield yog 37.5%).
