ʻAkika Adipic Dihydrazide (ADH) Hale Hana & Mea Hoʻolako

ʻAkika Adipic Dihydrazide(ADH) he mea hoʻohuihui o nā emulsions acryl i lawe ʻia e ka wai. He mea pono nō hoʻi ia ma ke ʻano he mea hoʻopaʻakikī resin epoxy a he mea hoʻoheheʻe formaldehyde. ʻO ADH (Adipic acid dihydrazide) kahi hui organik me ke ʻano kemika C₆H₁₀N₂O₂, a no ka papa o hydrazides. Hoʻohana nui ʻia ia i ka hoʻomākaukau ʻana o nā polyurethanes, nā mea polymeric, a ma nā noi ʻoihana ʻē aʻe ma muli o kona hiki ke hana me nā hui hana like ʻole e hana i nā pūnaewele i hoʻohuihui ʻia.

1. ʻAno Molekala o ka Adipic Acid Dihydrazide (ADH)

ʻO ke ʻano o ka Adipic Acid Dihydrazide:

• ʻAkika Adipic(kahi waikawa dicarboxylic ʻeono-kalapona, C₆H₁₀O₄) i hoʻololi ʻia ma ka hoʻopili ʻana i ʻelua mau hui hydrazine (-NH-NH₂) i nā hui carboxyl o ka waikawa.

• Hiki ke hōʻike ʻia ke ʻano kemika o ADH penei:

  HOOC-(CH₂)₄-CO-NH-NH₂

  He dihydrazide ia, ʻo ia hoʻi, ua hoʻopaʻa ʻia kēlā me kēia o nā hui carboxyl ʻelua (–COOH) o ka waikawa adipic i hoʻokahi hui hydrazine (–NH–NH₂).

ʻO ka hopena o ka hoʻonohonoho ʻana he kikowaenaiwi kuamoʻo waikawa adipic, me nā hui hana hydrazine ma kēlā me kēia hopena, e hoʻolilo ana iā ADH i mea hoʻohui koʻikoʻi i nā hopena kemika like ʻole.

2. Hana ʻia ʻana o ka Adipic Acid Dihydrazide

ʻO ka hana ʻana o ADH e pili ana i ka hopena o ka waikawa adipic me ka hydrazine hydrate. Hiki ke ho'ākāka 'ia nā hana no ka hana ʻana penei:

1. Ka hopena o ka waikawa Adipic me ka HydrazineHoʻopili ʻia ka waikawa Adipic me ka nui o ka hydrazine hydrate (NH₂-NH₂·H₂O) i loko o kahi mea hoʻoheheʻe kūpono (e like me ka ethanol a i ʻole ka wai) ma lalo o nā kūlana i kāohi ʻia (e laʻa, ka mahana kiʻekiʻe).

2. Hoʻokumu ʻia ʻana o DihydrazideHoʻopili nā hui hydrazine i nā hui carboxyl ʻelua o ka waikawa adipic, e hana ana i ka Adipic Acid Dihydrazide.

3. Hoʻomaʻemaʻe ʻanaA laila hoʻomaʻemaʻe ʻia ka huahana, ma ke ʻano maʻamau ma o ka recrystallization, e wehe i nā reagents i hana ʻole ʻia a loaʻa ka ADH maʻemaʻe.

Hiki ke hōʻike ʻia ka hopena penei:

HOOC-(CH₂)₄-COOH + 2 NH₂-NH₂ → HOOC-(CH₂)₄-CO-NH-NH₂ (ADH)

3. Nā Waiwai o ka Adipic Acid Dihydrazide

4. Nā Hoʻohana ʻana o Adipic Acid Dihydrazide (ADH)

Hoʻohana ʻia ka Adipic Acid Dihydrazide i nā ʻano hana ʻoihana like ʻole ma muli o kona mau waiwai kemika kūikawā:

4.1. Hana ʻana i ka Polyurethane

Hoʻohana ʻia ʻo ADH ma ke ʻano he lāʻau lapaʻaumea hoʻōlaa i ʻole ka mea hoʻopili ʻana i ka hana ʻana opolyurethanenā mea hana. Hiki i nā hui hydrazide ke hana me nā isocyanates e hana i nā crosslinks paʻa, kahi e hoʻonui ai i ka ikaika, ka maʻalahi, a me ke kūpaʻa o nā huahana polyurethane. He mea pono loa ʻo ADH i nā noi e pono ai nā polyurethanes thermosetting, e like me nā uhi, nā mea hoʻopili, a me nā mea hoʻopaʻa.

4.2. Hana ʻana o nā mea Polymeric

Ma waho aʻe o nā polyurethanes, hiki ke hoʻohana ʻia ʻo ADH i ka hoʻomākaukau ʻana o nā mea ʻē aʻe.nā pūnaewele polymericʻO kona ʻano dihydrazide e hiki ai iā ia ke komo i nā ʻano hana like ʻole, e like me nā aldehydes, ketones, a i ʻole nā ​​​​carboxylic acids, e hana i nā polymers i hoʻopili nui ʻia. Hoʻohana ʻia kēia waiwai i ka hoʻomākaukau ʻana o nā polymeric hydrogels a me nā mea hana kūikawā ʻē aʻe.

4.3. Nā Hana Hana ma muli o ka Hydrazide

He pane nui ka hui hydrazide (-NH-NH₂) ma ADH i nā hui carbonyl (e like me nā aldehydes a me nā ketones), e ʻae ana iā ADH e hoʻohana ʻia i ka synthesis o nā ʻano like ʻole.nā mea i loaʻa mai ka hydrazoneHe mau mea koʻikoʻi nā Hydrazones i ka synthesis organik a hiki ke hoʻohana ʻia i ka kemika lāʻau lapaʻau a me ka ʻepekema mea.

4.4. Nā noi lāʻau lapaʻau a me Biomedical

I kekahi manawa ua ʻike ʻia ʻo ADH i loko o ka ʻōpū.nā kahua lāʻau lapaʻau a me nā biomedical, kahi e hana ai kona reactivity me nā hui carbonyl i mea e pono ai ke kūkulu ʻia i ka hoʻolālā ʻana o kekahi maunā ʻōnaehana hoʻouna lāʻau lapaʻau or nā mea biocompatibleUa aʻo ʻia nā mea i hoʻokumu ʻia i ka ADH no ka hoʻohana ʻana i lokonā hydrogels biodegradable, hiki ke hoʻohana ʻia i ka hoʻokuʻu ʻana i nā lāʻau lapaʻau i kāohi ʻia a i ʻole nā ​​​​noi ʻenekinia ʻiʻo.

4.5. Mea Hoʻopili i nā Hydrogels

Hiki iā ADH ke lawelawe ma ke ʻano hemea hoʻopilino ka hana ʻana onā hydrogels, i hoʻohana ʻia i nā noi lapaʻau like ʻole e like me nā ʻaʻahu ʻeha, nā aniani hoʻopili, a me nā ʻōnaehana lāʻau lapaʻau hoʻokuʻu-i kāohi ʻia. ʻO ka hoʻokumu ʻia ʻana o kahi pūnaewele ʻekolu-dimensional ma o nā loulou hydrazone a i ʻole hydrazide e hoʻonui i ke kūpaʻa a me ka hana o ka hydrogel.

4.6. Hana ʻia ʻana o nā Polyesters a me nā Polyamides

Hoʻohana ʻia nō hoʻi ʻo ADH i ka hoʻomākaukau ʻana onā polyestera menā polyamidesma o nā hopena polycondensation. Hiki i ka hui hydrazide o ADH ke hana me nā diacids a i ʻole diols, e kōkua ana i ka hoʻokumu ʻana o nā kaulahao polymer. Hiki ke hoʻohana ʻia kēia i ka hana ʻana o nā polyamides kūikawā a i ʻole polyesters no ka hana ʻenekinia ʻana i nā plastics a me nā uhi.

4.7. Mahiʻai

I kekahi mau hihia, hoʻohana ʻia ka ADH i loko o kanā kemika mahiʻai, ʻoi aku hoʻi i ka hoʻomākaukau ʻana i nā ʻano hana no nā pesticides a i ʻole nā ​​​​herbicides e pono ai ka hoʻonui ʻia ʻana o ke kūpaʻa kemika a i ʻole ka hoʻokuʻu ʻana i kāohi ʻia. ʻO kona hiki ke hana i nā pūnaewele crosslinked hiki ke hoʻomaikaʻi i ka hana a me ka lawe ʻana i nā mea hana i nā huahana mahiʻai.
