daahirglacial acetic acid, taas oo ah, anhydrous acetic acid, acetic acid waa mid ka mid ah acids organic muhiim ah, xeryahooda organic. Waxay ku adkeysataa baraf heerkul hooseeya waxaana badanaa loo yaqaannaaglacial acetic acid. Barafka qaboojinta waa 16.6° C (62° F), iyo adkeynta ka dib, waxay noqotaa crystal aan midab lahayn. Xalkeeda aqueous waa aashito daciif ah oo aad u daxalaysa, oo aad bay u daxalisaa biraha. Uumiga ayaa saameyn cuncun leh ku leh indhaha iyo sanka. Haddaba, maxay yihiin isticmaalka gaarka ah glacial acetic acidwarshado kala duwan?
Marka hore, isticmaalka warshadaha glacial acetic acid
1. Loo isticmaalo dheeha synthetic iyo khadadka.
2. Warshadaha cuntada, waxa loo istcimaalaa habeeyaha aashitada, aashitada, wakiilka qajaarka, dhadhanka kor u qaada, xawaashka iyo wixii la mid ah. Sidoo kale waa wakiilka antimicrobial wanaagsan, inta badan ay sabab u tahay awoodda ay u leedahay in la yareeyo pH ka hooseeya pH looga baahan yahay koritaanka microbial fiicnayn.
3. Waxaa loo isticmaalaa warshadaha caagagga iyo caagagga. Waxa loo isticmaalaa sida dareere iyo walxo bilawga ah oo loogu talagalay polymers badan oo muhiim ah (sida PVA, PET, iwm.) ee warshadaha caagagga iyo caagagga.
4. Waxaa loo isticmaalaa sidii qalab bilow ah oo loogu talagalay rinjiga iyo maaddooyinka dhejiska ah.
5. Glacial acetic acid sidoo kale waxay door muhiim ah ka ciyaartaa dhar-dhaqidda, inta badan waxay ka hortagtaa luminta midabka dharka, waxay si xoog leh uga saartaa wasakhda, waxayna ka takhalusi kartaa pH.glacial acetic acid ayaa caan ku ah dhar-dhaqashada. Marka la isticmaalayo, waxay u baahan tahay in loo isticmaalo si waafaqsan tilmaamaha qaarkood, oo aan si indho la'aan ah loo isticmaali karinglacial acetic acid.
Labaad,glacial acetic acid isticmaalka kiimikaad
1. Waayo, synthesize of acetate cellulose. Cellulose acetate waxaa loo isticmaalaa filimada sawirada iyo dunta. Kahor intaan la abuurin filimka acetate cellulose, filim sawireed ayaa loo isticmaali jiray in laga sameeyo Nitrate waxaana jiray walaac badan oo badbaado ah.
2. Loo isticmaalo sida dareere loogu talagalay isku dhafka terephthalic acid. P-xylene waxa ay oksidhisaydh ku noqotay terephthalic acid. Terephthalic acid waxaa loo isticmaalaa isku dhafka PET waxaana si weyn loogu isticmaalaa soo saarista dhalooyinka caaga ah.
3. Si ballaaran loo isticmaalo in lagu farsameeyo esters iyadoo laga falcelinayo aalkolada kala duwan. Kala soocida Acetate ayaa si weyn loo isticmaalaa sida cuntada lagu daro.
4. Waxaa loo isticmaalaa isku-dhafka vinyl acetate monomer. monomer-ka ayaa markaa noqon kara polymerized si uu u sameeyo poly (vinyl acetate), oo sidoo kale loo yaqaan PVA.
5. Loo isticmaalo sida dareere ah falcelinno katalytic organic badan.
6. Waxaa loo istcimaalaa sidii miisaan iyo ka saarida miridhku. Goormaacetic acidla falgala biyo, cuncunka miisaanka iyo goobooyinku way baaba'aan, iyaga oo ka soo jejebiya adkaha oo u noqda dareere si fudud loo saari karo.
