Ƙwararren gwagwarmaya ga glycerin shine takamaiman, yana taimakawa wajen gano shi

Glycerin ko kuma, bisa ga ƙididdigar ƙasashen duniya, propantriol -1,2,3 abu ne mai mahimmanci wanda ke da polyhydric alcohols, ko kuma mafi daidai shine barasa na trihydric, Yana da 3 hydroxyl kungiyoyi - OH. A sunadarai Properties na glycerol ne kamar irin waɗanda na monoalcohols, amma acidic Properties ne mafi pronounced saboda gaskiyar cewa hydroxyl kungiyar more kuma suka yi tasiri juna.

Glycerin, kamar masu maye gurbi tare da rukunin hydroxyl daya, ya rushe sosai cikin ruwa. Wannan, ana iya ce, shi ma ya cancanci gwagwarmaya ga glycerin, yayin da yake rushewa cikin ruwa a kusan kowane rabo. Ana amfani da wannan dukiya wajen samar da ƙyama - wadatar da ba sa daskare da kuma kwantar da motar motoci da jirgin sama.

Har ila yau glycerin yayi hulɗa da potassium permanganate. Wannan ƙwararre ne ga glycerin, wanda ake kira Dutsen mai tsabta. Don gudanar da shi, kana buƙatar foda potassium, wanda aka zubar da shi ta hanyar zanewa tare da zurfafa a cikin tanda mai naman, ƙara 1-2 saukad da glycerin anhydrous. Bayan minti daya kwakwalwar ta lalata wuta tare da harshen wuta. A lokacin dauki, ana fitar da babban adadin zafi, kazalika da yanayin zafi na samfurori da samfurori. Wannan aikin ne redox.

Glycerin yana da hygroscopicity, i.e. Yana da damar riƙe da danshi. Yana da a kan wannan dukiya cewa irin wannan gagarumin gwagwarmaya na glycerin na tushen. An yi shi a cikin ɗakin wuta. Don halinsa a tsabtaccen jarrabawar busasshen ruwa game da 1 cm3 na crystalline potassium hydrogen sulfate (KHSO4). Ƙara 1-2 saukad da glycerin, to, zafin jiki har sai bayyanar wari mai ban sha'awa. Hydrosulfate na potassium yana aiki a nan a matsayin abu mai-ruwa, wanda zai fara nuna kansa yayin da yake mai tsanani. Glycerin, ruwa mai ɓata, an juya shi zuwa wani fili mai ƙinƙasa - acrolein, wanda yana da wari mai ban sha'awa. Reaction lissafi: S3N5 (OH) 3 - H2C = CH-Cho + 2 H2O.

Reaction of glycerol da tagulla hydroxide ne ingantaccen da kuma hidima domin sanin ba kawai glycerol amma sauran polyols. Domin gudanar da shi, dole ne ku fara shirya wani bayani mai kyau na jan karfe hydroxide (II). Don wannan karshen, jan karfe sulfate kara sodium hydroxide kuma samu jan hydroxide, jan (II), wanda Forms blue precipitate. A cikin wannan bututun tare da sutura ƙara ƙananan saukad da glycerin kuma ya lura cewa precipitate bace, da kuma bayani ya samo launin launi mai launi. An kira wannan hadaddiyar giya ne ko glycerate jan karfe. Ana amfani da samfurori ga glycerin tare da jan karfe (II) hydroxide idan glycerin yana cikin tsabta ko a cikin bayani mai ruwa. Don aiwatar da irin wannan halayen, wanda glycerine yake tare da marasa tsarki, dole ne a gudanar da tsarkakewa na farko daga gare ta.

Ayyuka masu dacewa don taimakon glycerin don gano shi a kowane yanayi. An yi amfani da shi don amfani da glycerin a abinci, kayan shafawa, turare, shirye-shiryen kiwon lafiya da kuma ƙyama.
