Qhov sib txawv tseem ceeb ntawm imidazolidnyl urea thiab diazolidinyl urea yog tias imidazolidnyl urea molecule muaj ob lub nplhaib imidazolidine whereas diazolidinyl urea molecule muaj ib lub nplhaib imidazolidine.
Imidazolidnyl urea thiab diazolidinyl urea molecules yog tshuaj lom neeg sib raug zoo vim lawv muaj tib lub qauv cyclic.
YImidazolidinyl Urea yog dab tsi?
Imidazolidinyl urea yog cov tshuaj tua kab mob tua kab mob uas tuaj yeem siv tau hauv kev lag luam tshuaj pleev ib ce. Cov tshuaj no muaj feem xyuam nrog Diazolidinyl urea tshuaj. Ntxiv mus, qhov sib xyaw no tuaj yeem ua raws li formaldehyde tso tawm, ib yam li Diazolidinyl urea. Qee tus neeg pom kev ua xua rau ob qho tib si imidazolidinyl urea thiab diazolidinyl urea, uas tuaj yeem ua rau dermatitis.
Daim duab 01: Cov qauv ntawm Imidazolidinyl Urea
Thaum xav txog cov qauv tshuaj ntawm cov tshuaj no, nws muaj ob lub imidazolidine rings, thiab lawv cov hydroxymethyl functional pawg tau txuas rau cov pa roj carbon atoms es tsis yog nitrogen atoms.
Ntxiv mus, imidazolidinyl urea tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm allantoin thiab formaldehyde nyob rau hauv muaj sodium hydroxide (NaOH) tov thiab cua sov. Ntawm no, ob lub allantoin molecules react nrog peb formaldehyde molecules muab ib imidazolidinyl urea molecule.
YDiazolidinyl Urea yog dab tsi?
Diazolidinyl urea yog cov organic compound uas yog ib qho tseem ceeb raws li cov tshuaj tiv thaiv kab mob muaj txiaj ntsig zoo hauv kev lag luam tshuaj pleev ib ce. Cov tshuaj no muaj feem xyuam rau imidazolidinyl urea tshuaj. Ob lub tebchaw no siv tib txoj kev. Diazolidinyl urea yog siv los ua ib qho formaldehyde tso tawm. Tsis tas li, nws muaj txiaj ntsig zoo hauv kev tsim khoom ntawm ntau yam khoom hauv kev lag luam tshuaj pleev ib ce, nrog rau cov khoom tu tawv nqaij, tshuaj zawv plaub hau, tshuaj pleev ib ce. Tsis tas li ntawd, peb tuaj yeem pom cov tshuaj no hauv ntau yam khoom xws li cov da dej ua npuas dej, cov ntaub so me nyuam thiab cov tshuaj ntxuav tsev neeg. Kev lag luam, qhov sib xyaw no muaj nyob rau hauv kev khaws cia hu ua "Germaben". Hauv nws qib kev lag luam, nws tshwm sim raws li kev sib xyaw ntawm cov khoom sib txawv formaldehyde ntxiv xws li polymers.
Daim duab 02: Tsis ntev los no pom cov qauv tshuaj ntawm Diazolidinyl Urea
Thaum xav txog kev tsim cov diazolidinyl urea, feem ntau txoj hauv kev yog cov tshuaj tiv thaiv ntawm allantoin thiab formaldehyde nyob rau hauv muaj cov tshuaj NaOH (Sodium hydroxide) thiab cua sov. Tom qab ntawd, peb tuaj yeem tshem tawm cov tshuaj no sib tov siv hydrochloric acid (HCl acid), ua raws li cov kauj ruam evaporation. Ntawm no, ib qho allantoin molecule reacts nrog plaub formaldehyde molecules muab ib diazolidinyl urea molecule.
Raws li cov ntaub ntawv tsis ntev los no hais txog diazolidinyl urea molecule, cov pawg hydroxymethyl ua haujlwm ntawm lub nplhaib imidazolidine hauv qhov sib xyaw no txuas nrog cov pa roj carbon atom es tsis yog nitrogen atom hauv pawg urea.
Ntxiv mus, peb yuav tsum xav txog kev nyab xeeb ntawm kev siv cov tshuaj diazolidinyl urea. Qhov no yog vim qee tus neeg pom kev ua xua rau cov urea compound, uas tuaj yeem ua rau mob dermatitis. Tsis tas li ntawd, nws tuaj yeem suav hais tias yog tus neeg sawv cev carcinogenic vim tias nws yog formaldehyde tso tawm uas tuaj yeem tso cov carcinogen formaldehyde thaum maj mam degrading nws tus kheej.
Dab tsi yog qhov zoo sib xws ntawm Imidazolidinyl Urea thiab Diazolidinyl Urea?
- Imidazolidinyl urea thiab Diazolidinyl urea muaj imidazolidine nplhaib qauv.
- Ob leeg yog ib qho tseem ceeb ua cov tshuaj tiv thaiv kab mob.
- Peb tuaj yeem siv cov tshuaj no hauv kev tsim khoom kom zoo nkauj.
- Ob leeg tuaj yeem ua raws li formaldehyde tso tawm.
Qhov txawv ntawm Imidazolidinyl Urea thiab Diazolidinyl Urea yog dab tsi?
Imidazolidnyl urea thiab diazolidinyl urea molecules yog tshuaj lom neeg sib raug zoo. Qhov sib txawv tseem ceeb ntawm imidazolidnyl urea thiab diazolidinyl urea yog tias imidazolidnyl urea molecule muaj ob lub imidazolidine rings whereas diazolidinyl urea molecule muaj ib lub nplhaib imidazolidine.
Cov ntaub ntawv hauv qab no-daim duab tabulates qhov sib txawv ntawm imidazolidnyl urea thiab diazolidinyl urea.
Summary – Imidazolidinyl Urea vs Diazolidinyl Urea
Ob qho tib si imidazolidnyl urea thiab diazolidinyl urea molecules tuaj yeem ua cov tshuaj formaldehyde tso tawm vim tias lawv muaj cov qauv zoo sib xws. Qhov sib txawv tseem ceeb ntawm imidazolidnyl urea thiab diazolidinyl urea yog tias imidazolidnyl urea molecule muaj ob lub imidazolidine rings whereas diazolidinyl urea molecule muaj ib lub nplhaib imidazolidine.
