Adipic Acid Dihydrazide (ADH)
Adipic Acid Dihydrazide (ADH) Warshadda & Alaab-qeybiyaha
Adipic Acid Dihydrazide(ADH) waa isku xidhe ka samaysan emulsions-ka acryl ee biyaha ku jira. Waxa kale oo ay faa'iido u leedahay sida adkeyaha resin epoxy iyo qashin-qubka formaldehyde. ADH（Adipic acid dihydrazide）waa isku-dhis dabiici ah oo leh qaacidada kiimikada C₆H₁₀N₂O₂, waxayna ka tirsan tahay fasalka hydrazides. Waxaa ugu horreyn loo isticmaalaa diyaarinta polyurethanes, walxaha polymeric-ga, iyo codsiyada kale ee warshadaha sababtoo ah awooddeeda ay kula falgasho kooxo kala duwan oo shaqeynaya si ay u sameeyaan shabakado isku xiran.

1. Qaab-dhismeedka Molekule ee Adipic Acid Dihydrazide (ADH)
Qaab-dhismeedka Adipic Acid Dihydrazide wuxuu ka kooban yahay:
-
Adipic acid(asiidh dicarboxylic lix-kaarboon ah, C₆H₁₀O₄) oo wax laga beddelay iyadoo lagu dhejinayo laba kooxood oo hydrazine ah (-NH-NH₂) kooxaha carboxyl ee aashitada.
-
Qaab-dhismeedka kiimikada ee ADH waxaa lagu matali karaa sidan:
HOOC-(CH₂)₄-CO-NH-NH₂
Waa dihydrazide, taasoo la micno ah in mid kasta oo ka mid ah labada kooxood ee carboxyl (–COOH) ee adipic acid uu ku xiran yahay hal koox oo hydrazine ah (–NH–NH₂).
Qaab-dhismeedka ka soo baxay wuxuu ka kooban yahay xarun dhexelaf-dhabarta adipic acid, iyadoo kooxaha shaqeynaya ee hydrazine ay dhinac kasta ku yaalliin, taasoo ka dhigaysa ADH mid muhiim u ah falgallada kiimikada ee kala duwan.
2. Isku-darka Adipic Acid Dihydrazide
Sameynta ADH waxay caadi ahaan ku lug leedahay falgalka adipic acid oo ay weheliso hydrazine hydrate. Tallaabooyinka isku-darka waxaa lagu qeexi karaa sidan soo socota:
-
Falcelinta Adipic Acid oo leh HydrazineAdipic acid waxaa lagu falceliyaa xad-dhaaf ah oo ah hydrazine hydrate (NH₂-NH₂·H₂O) oo ku jira dareere ku habboon (sida ethanol ama biyo) xaaladaha la xakameeyey (tusaale ahaan, heerkulka oo sarreeya).
-
Samaynta DihydrazideKooxaha hydrazine-ku waxay ku dheggan yihiin labada kooxood ee carboxyl ee adipic acid, iyagoo sameeya Adipic Acid Dihydrazide.
-
NadiifintaDabadeed badeecada ayaa la nadiifiyaa, badanaa iyadoo dib loo warshadaynayo, si looga saaro falgalayaasha aan falcelinta lahayn loona helo ADH saafi ah.
Falcelinta waxaa lagu matali karaa sidan:
HOOC-(CH₂)₄-COOH + 2 NH₂-NH₂ → HOOC-(CH₂)₄-CO-NH-NH₂ (ADH)

4. Isticmaalka Adipic Acid Dihydrazide (ADH)
Adipic Acid Dihydrazide waxaa loo isticmaalaa noocyo kala duwan oo warshadeed sababtoo ah sifooyinka kiimikada ee gaarka ah:
4.1. Soosaarka Polyurethane
ADH waxaa loo isticmaalaa sidawakiilka daaweyntaama wakiil isku xidha wax soo saarkapolyurethaneagabyada. Kooxaha hydrazide-ku waxay la falgeli karaan isocyanates si ay u sameeyaan isku-xirro deggan, kuwaas oo kor u qaada xoogga, dabacsanaanta, iyo cimri dhererka alaabada ku salaysan polyurethane. ADH waxay si gaar ah waxtar ugu leedahay codsiyada u baahan polyurethanes-ka kuleylka dejiya, sida dahaarka, dhejiska, iyo shaabadaha.
4.2. Isku-darka Agabka Polymeric-ka
Marka laga soo tago polyurethanes, ADH waxaa loo isticmaali karaa diyaarinta kiimikooyinka kale.shabakadaha polymericQaab-dhismeedkeeda dihydrazide wuxuu u oggolaanayaa inuu ka qaybqaato falcelinno kala duwan, sida aldehydes, ketones, ama asiidhyada carboxylic, si loo sameeyo polymers aad isugu xiran. Sifadan waxaa loo isticmaalaa diyaarinta hydrogels polymeric iyo agab kale oo gaar ah.
4.3. Falcelinta ku salaysan Hydrazide
Kooxda hydrazide (-NH-NH₂) ee ADH waxay si aad ah uga falcelisaa kooxaha carbonyl (sida aldehydes iyo ketones), taasoo u oggolaanaysa ADH in loo isticmaalo isku-darka noocyo kala duwan oo kiimikooyin ah.waxyaabaha ka soo baxa hydrazoneHydrazones waa dhexdhexaad muhiim ah oo ku jira isku-darka dabiiciga ah waxaana loo isticmaali karaa kiimikada dawooyinka iyo sayniska agabka.
