Adipic Acid Dihydrazide (ADH)
Adipic Acid Dihydrazide (ADH) Fektheri le Mofani
Adipic Acid Dihydrazide(ADH) ke crosslinker ea li-emulsion tsa acryl tse tsamaisoang ke metsi. E boetse e na le thuso e le epoxy resin hardener le formaldehyde scavenger. ADH（Adipic acid dihydrazide）ke motsoako oa lintho tse phelang o nang le foromo ea lik'hemik'hale C₆H₁₀N₂O₂, 'me ke oa sehlopha sa li-hydrazide. E sebelisoa haholo-holo ho lokiseng li-polyurethane, thepa ea polymeric, le lits'ebetsong tse ling tsa indasteri ka lebaka la bokhoni ba eona ba ho arabela le lihlopha tse fapaneng tse sebetsang ho theha marang-rang a hokahaneng.

1. Sebopeho sa limolek'hule tsa Adipic Acid Dihydrazide (ADH)
Sebopeho sa Adipic Acid Dihydrazide se na le:
-
Asiti ea Adipic(esiti ya dicarboxylic ya khabone e tsheletseng, C₆H₁₀O₄) e fetotsweng ka ho hokela dihlopha tse pedi tsa hydrazine (-NH-NH₂) ho dihlopha tsa carboxyl tsa asiti.
-
Sebopeho sa lik'hemik'hale sa ADH se ka emeloa e le:
HOOC-(CH₂)₄-CO-NH-NH₂
Ke dihydrazide, ho bolelang hore sehlopha se seng le se seng sa dihlopha tse pedi tsa carboxyl (–COOH) tsa adipic acid se tlameletsoe sehlopheng se le seng sa hydrazine (–NH–NH₂).
Sebopeho se hlahang se na le karolo e boharenglesapo la mokokotlo la asiti ea adipic, ka lihlopha tse sebetsang tsa hydrazine pheletsong ka 'ngoe, e leng se etsang hore ADH e be reagent ea bohlokoa liketsong tse fapaneng tsa lik'hemik'hale.
2. Ho kopanngoa ha Adipic Acid Dihydrazide
Ho kopanngoa ha ADH hangata ho kenyelletsa karabelo ea adipic acid le hydrazine hydrate. Mehato ea ho kopanngoa e ka hlalosoa ka tsela e latelang:
-
Karabelo ea Adipic Acid le Hydrazine: Asiti ea Adipic e arajoa ka hydrazine hydrate e ngata (NH₂-NH₂·H₂O) ka har'a solvent e loketseng (joalo ka ethanol kapa metsi) tlas'a maemo a laoloang (mohlala, mocheso o phahameng).
-
Ho thehoa ha DihydrazideLihlopha tsa hydrazine li hokahane le lihlopha tse peli tsa carboxyl tsa adipic acid, li etsa Adipic Acid Dihydrazide.
-
Tlhoekiso: Sehlahisoa se hloekisoa, hangata ka ho se sebelisa hape, ho tlosa li-reagent tse sa arajoang le ho fumana ADH e hloekileng.
Karabelo e ka emeloa e le:
HOOC-(CH₂)₄-COOH + 2 NH₂-NH₂ → HOOC-(CH₂)₄-CO-NH-NH₂ (ADH)

4. Ts'ebeliso ea Adipic Acid Dihydrazide (ADH)
Adipic Acid Dihydrazide e sebelisoa lits'ebetsong tse fapaneng tsa indasteri ka lebaka la thepa ea eona e ikhethang ea lik'hemik'hale:
4.1. Tlhahiso ea Polyurethane
ADH e sebelisoa e lesesebelisoa sa ho folisakapa moemeli oa khokahano tlhahisong eapolyurethanethepa. Lihlopha tsa hydrazide li ka arabela ka li-isocyanate ho theha lihokelo tse tsitsitseng, tse ntlafatsang matla, ho tenyetseha le ho tšoarella ha lihlahisoa tse thehiloeng ho polyurethane. ADH e na le thuso haholo-holo lits'ebetsong tse hlokang li-polyurethane tse sebelisang thermosetting, joalo ka ho koahela, likhomaretsi le li-sealant.
4.2. Ho kopanngoa ha Lisebelisoa tsa Polymeric
Ntle le polyurethanes, ADH e ka sebelisoa ho lokiseng tse lingmarangrang a polymericSebopeho sa yona sa dihydrazide se e dumella ho nka karolo dikarabelong tse fapaneng, tse kang di-aldehydes, di-ketone, kapa di-carboxylic acid, ho theha di-polymer tse hokahaneng haholo. Thepa ena e sebediswa ho lokiseng di-hydrogel tsa polymer le thepa e nngwe e ikgethang.
4.3. Likarabelo tse Thehiloeng ho Hydrazide
Sehlopha sa hydrazide (-NH-NH₂) ho ADH se arabela haholo ho lihlopha tsa carbonyl (tse kang aldehydes le ketones), e leng se lumellang ADH ho sebelisoa ho etseng metsoako e fapaneng.lintho tse tsoang ho hydrazoneLi-hydrazone ke lintho tsa bohlokoa tse bohareng ba motsoako oa lintho tse phelang 'me li ka sebelisoa k'hemistri ea meriana le saense ea thepa.
4.4. Litšebeliso tsa Meriana le tsa Bongaka
Ka linako tse ling ADH e hlahlojoamasimo a meriana le a bongaka, moo ho sebetsana ha eona le lihlopha tsa carbonyl ho e etsang hore e be motheo o thusang oa kaho moralong oa lintho tse itsenglitsamaiso tsa ho fana ka lithethefatsi or thepa e lumellanang le lintho tse phelangLisebelisoa tse thehiloeng ho ADH li ithutiloe bakeng sa tšebeliso holi-hydrogel tse bolang, e ka sebelisoang lits'ebetsong tsa ho lokolla lithethefatsi tse laoloang kapa tsa boenjiniere ba lisele.
4.5. Moemeli oa ho hokahanya li-Hydrogel
ADH e ka sebetsa e lemoemeli oa ho hokahanyabakeng sa tlhahiso eali-hydrogel, tse sebediswang ditshebedisong tse fapaneng tsa bongaka tse kang di-dressing tsa maqeba, dilense tsa mahlo, le ditsamaiso tsa meriana e lokollwang ka taolo. Ho thehwa ha marangrang a mahlakore a mararo ka dihokelo tsa hydrazone kapa hydrazide ho ntlafatsa botsitso le tshebetso ya hydrogel.
4.6. Ho kopanngoa ha Polyester le Polyamide
ADH e boetse e sebelisoa ha ho lokisoali-polyesterleli-polyamideka dikarabelo tsa polycondensation. Sehlopha sa hydrazide sa ADH se ka arabela le diacid kapa diol, e leng se thusang ho thehwa ha diketane tsa polymer. Sena se ka sebediswa tlhahisong ya di-polyamide kapa di-polyester tse ikgethang bakeng sa dipolasetiki le dikobo tsa boenjiniere.
4.7. Temo
Maemong a mang, ADH e sebelisoa holik'hemik'hale tsa temo, haholo-holo ho lokiseng metsoako ea chefo e bolaeang likokoanyana kapa meriana e bolaeang likokoanyana e hlokang botsitso bo matlafalitsoeng ba lik'hemik'hale kapa tokollo e laoloang. Bokhoni ba eona ba ho theha marang-rang a hokahaneng bo ka ntlafatsa ts'ebetso le phano ea metsoako e sebetsang lihlahisoa tsa temo.
