Cationic surfactants badanaa waa walxo amine dabiici ah oo ka kooban nitrogen. Maadaama atamka nitrogen ee ku jira molecules-kooda uu ka kooban yahay labo elektaroono oo keliya, waxay ku biiri kartaa haydarojiin ee ku jira molecules-ka aashitada iyada oo loo marayo isku-xidhka haydarojiin, taasoo keenta in kooxda amino-ku ay qaadaan dallac wanaagsan. Sidaa darteed, waxay muujiyaan oo keliya firfircooni dusha sare oo wanaagsan oo ku jirta warbaahinta aashitada; warbaahinta alkaline-ka, waxay u muuqdaan inay soo daadiyaan oo ay lumiyaan dhaqdhaqaaqooda dusha sare. Marka laga soo tago surfactants cationic-ka ku jira nitrogen, waxaa sidoo kale jira qayb yar oo ka mid ah surfactants cationic oo ka kooban walxo sida sulfur, fosfooraska, iyo arsenic.
1. Xaaladda horumarinta
Cationic surfactants si weyn looma isticmaalin warshadaha muddo dheer, baahidooduna si xawli ah ayay sanadba sanadka ka dambeeya u koraysay. Si kastaba ha ahaatee, maadaama adeegsigooda ugu muhiimsan uu yahay isticmaalka gaarka ah sida fungicides, jilciyeyaasha fiber-ka, iyo wakiilada ka hortagga istaatiijiyadda, isticmaalkoodu waa mid aad uga yar marka la barbar dhigo anionic iyo non-ionic surfactants.
Waxyaabaha loo yaqaan 'cationic surfactants' guud ahaan waxay leeyihiin sifooyin wanaagsan sida emulsification, qoynta, dhaqidda, nadiifinta, jilcinta, antistatic, iyo ka hortagga daxalka. Sababo la xiriira sifooyinkooda gaarka ah iyo codsiyada, waxay leeyihiin awood horumarineed oo wanaagsan. Maadaama baaxadda codsiyada warshadaha iyo kuwa madaniga ah ay sii ballaaranayso, noocyada iyo baahidoodu way sii kordhayaan.
2. Kala-soocidda
Inta badan surfactants-ka cationic-ga leh qiimaha ganacsiga waa kuwa ka soo jeeda isku-dhafka nitrogen-ka dabiiciga ah, halkaas oo dallacaadda togan ay qaadaan atamka nitrogen-ka. Waxaa sidoo kale jira noocyo cusub oo surfactants cationic ah halkaas oo dallacaadda togan ay qaadaan atamka sida fosfooraska, sulfur, iodine, iyo arsenic. Sida laga soo xigtay qaab-dhismeedka kiimikada ee surfactants-ka cationic-ga, waxaa inta badan loo qaybin karaa afar qaybood: nooca cusbada amine, nooca cusbada ammonium-ka quaternary, iyo nooca heterocyclic.
Surfactants-ka nooca milixda ee Amine waa erey guud oo loogu talagalay milixda amine ee aasaasiga ah, milixda amine ee labaad, iyo milixda amine ee saddexaad. Sifooyinkoodu aad bay isugu egyihiin, badeecooyin badanna waa isku darka amines-ka aasaasiga ah iyo amines-ka labaad. Noocan surfactant-ka ah wuxuu inta badan yahay milixyo ay sameeyaan amines-ka dufanka leh iyo asiidhyada aan organic ahayn, waxaana lagu milmaa oo keliya xalalka aashitada leh. Xaaladaha alkaline-ka, milixda amine-ku si fudud ayay ula falgalaan alkalis-ka si ay u sameeyaan amines-ka xorta ah, taas oo yareysa milmidooda, sidaas darteedna xaddidaysa baaxadda codsigooda ilaa xad gaar ah.
Nooca cusbada ammonium ee Quaternary
Surfactants-ka nooca cusbada ammonium ee Quaternary waa nooca ugu muhiimsan ee surfactants-ka cationic, iyadoo leh sifooyin iyo habab diyaarin oo ka duwan kuwa nooca cusbada amine. Surfactants-ka noocan oo kale ah waxay ku milmi karaan xalalka aashitada iyo alkaline labadaba, waxay leeyihiin taxane sifooyin aad u fiican, waxayna leeyihiin iswaafajin wanaagsan oo ay la leeyihiin noocyada kale ee surfactants-ka. Sidaa darteed, waxay leeyihiin codsiyo badan oo kala duwan.
Hnooca eterocyclic
Giraangiraha heterocyclic-ga ah ee ku jira molecules-ka surfactant-ka cationic waa kuwa ugu badan ee ka kooban nitrogen sida giraanta morpholine, giraanta pyridine, giraanta imidazole, giraanta piperazine iyo giraanta quinoline.
3. Isku-darka
Falcelinta ugu weyn ee lagu sameeyo isku-darka walxaha cationic waa falgalka N-alkylation. Kuwaas waxaa ka mid ah falgalka ay amiinada saddexaad la falgalaan wakiilada alkylating si ay u sameeyaan cusbooyinka ammonium ee quaternary waxaa sidoo kale loo yaqaan falgalka quaternization.
Cusbo ammonium quarternary ah oo alkyl ah
Cusbooyinka ammonium-ka ee Alkyl quaternary waa mid ka mid ah noocyada muhiimka ah ee surfactants-ka cusbada ammonium-ka ee nooca quaternary, waxaana si weyn loogu isticmaalay sidii fungicides, jilciyeyaasha fiber-ka, wakiilada sabbeynta macdanta, emulsifiers, iwm. Astaamahooda qaab-dhismeedka ayaa ah in atamka nitrogen-ku uu ku xiran yahay afar kooxood oo alkyl ah, taas oo ah, dhammaan afarta atamka hydrogen ee ammonium-ka waxaa lagu beddelaa kooxo alkyl ah. Caadiyan, hal ama laba ka mid ah kooxahan alkyl waa kooxo alkyl hydrocarbon silsilad dheer leh, kooxaha alkyl ee soo harayna waxay leeyihiin hal ama laba atamka kaarboon. Sida laga soo xigtay astaamahooda qaab-dhismeedka, waxaa inta badan jira saddex hab oo isku-darka ah oo loogu talagalay cusbooyinka alkyl quaternary ammonium: waxaa diyaariya falcelinta halides-ka alkyl-ka sare leh oo leh amiinada hoose ee hoose, oo lagu diyaariyey falcelinta amines-ka alkyl-ka sare leh oo leh halides-ka alkyl-ka hoose, waxaana lagu diyaariyey habka aashitada formaldehyde-formic.
Cusbooyinka ammonium ee Quaternary oo ka kooban heteroatoms
Cusbooyinka ammonium-ka ee quaternary oo ka kooban heteroatoms-ka halkan guud ahaan waxay tilmaamayaan cusbooyinka ammonium-ka ee quaternary kuwaas oo ka kooban heteroatoms sida O, N, iyo S silsiladahooda hydrocarbon-ka ee hydrophobic, taas oo ah, surfactants-ka ka kooban xidhmooyinka amide, xidhmooyinka ether, xidhmooyinka ester, ama xidhmooyinka thioether ee kooxahooda lipophilic. Maadaama kooxda cation-ka ammonium-ka ee hydrophilic iyo kooxda hydrophobic-ka ee alkyl ay ku xiran yihiin kooxo sida amide, ester, ether, ama thioether halkii ay si toos ah isugu xidhnaan lahaayeen, dadka qaar ayaa sidoo kale u yaqaana cusbooyinka ammonium-ka ee quaternary sida surfactants-ka cationic-ka ee si dadban isugu xidha.
Cusbo ammonium Quaternary ah oo ka kooban giraangiraha benzene
Noocan surfactant waxaa inta badan loo isticmaalaa sidii jeermis dile, wakiil xumbo, wakiil qoyn, iyo wakiil hagaajin rinji, iyo kuwo kale. Habka isku-darka, habka ugu weyn ee lagu soo bandhigo giraanta udgoonka waa in la isticmaalo benzyl chloride sidii reagent alkylating si loola falgalo amines-ka saddexaad. Benzyl chloride waxaa lagu diyaariyaa falgalka koloriinaynta silsiladda dhinaca ee toluene. Si looga fogaado koloriin ku dhaca giraanta benzene, falgalkan waxaa looga baahan yahay in lagu sameeyo kettle dhaldhalaal ah ama falgaliye munaarad ah oo galaas ku dahaaran.
Cusbooyinka ammonium ee Quaternary oo ka kooban wareegyo isku dhafan
Giraangiraha heterocyclic-ga ah ee ku jira molecules-ka cusbada ammonium-ka ee quaternary waa inta badan giraanta morpholine, giraanta piperazine, giraanta pyridine, giraanta quinoline iyo giraanta imidazole, iwm.
Anooca milixda macdanta
Surfactants-ka nooca milixda ee Amine-ka ah waxay inta badan ka kooban yihiin saddex qaybood oo waaweyn: cusbooyinka amine-ka aasaasiga ah ee alkyl-ka ee silsiladda dheer, cusbooyinka amine-ka labaad, iyo cusbooyinka amine-ka saddexaad.
4. Codsiga
Waxyaabaha loo yaqaan 'cationic surfactants' waxay leeyihiin shaqooyin wanaagsan sida nadiifinta, jilcinta,antistatic, iyo sifooyinka ka hortagga daxalka, iyo sidoo kale sifooyin gaar ah oo emulsifying iyo qoynta. Waxaa sidoo kale badanaa loo isticmaalaa sidii kiciyeyaasha wareejinta marxaladda. Si kastaba ha ahaatee, noocan surfactant-ka ah si dhif ah ayaa loo isticmaalaa kaligiis saabuun ahaan. Sababtoo ah dusha sare ee substrate-yo badan oo ku jira xalalka biyaha, gaar ahaan xalalka biyaha alkaline-ka ah, badanaa waxay qaadaan kharash taban. Inta lagu jiro codsiga, surfactant-ka si togan u dallacaya wuxuu ku habboonaan doonaa dusha sare ee substrate-ka iyadoo kooxaha hydrophilic-ga gudaha iyo kooxaha hydrophobic-ga dibadda, taasoo ka dhigaysa dusha sare ee substrate-ka hydrophobic, kaas oo aan ku habboonayn dhaqidda oo xitaa yeelan kara saameyn taban. Intaa waxaa dheer, goobaha ugu muhiimsan ee codsiga noocan ah ee surfactant-ka way ka duwan yihiin surfactants-ka kale, kuwaas oo loo isticmaalo in lagu yareeyo xiisadda dusha sare. Taa beddelkeeda, waxay u isticmaalaan astaamahooda qaab-dhismeedka codsiyada kale ee gaarka ah.
