Mea Hana a me ka Mea Hoʻolako Diacetone Acrylamide (DAAM)

ʻAcrylamida diacetoneʻO (DAAM) kahi hui kemika e pili ana i ka papa o nā derivatives acrylamide. Hoʻohana pinepine ʻia ia i ka kemika polymer a hiki ke hana ma ke ʻano he monomer i ka hana ʻana o nā polymers like ʻole, ʻoiai nā mea i hoʻohana ʻia i nā uhi, nā mea hoʻopili, a me nā composites. ʻO ke ʻano kemika o DAAM he hui acrylamide (kahi hui vinyl i hoʻopili ʻia i kahi hui carbonyl) a me kahi ʻāpana acetone.

Hiki ke ʻokoʻa nā waiwai o DAAM ma muli o kona polymerization. ʻO ka maʻamau, hoʻohana ʻia ʻo DAAM i ka synthesis o nā polymers me nā ʻano i makemake ʻia e like me ka hoʻomaikaʻi ʻana i ka hoʻopili ʻana, ka maʻalahi, a me ke kūʻē ʻana i nā mea pili i ke kaiapuni e like me ka wela a me ka makū.

ʻO kahi ʻano koʻikoʻi o DAAM ʻo ia kona hiki ke hana i ka polymerization radical free, kahi e hana ai me nā monomers ʻē aʻe (a i ʻole ia iho) e hana i nā polymers. Hiki ke hoʻohana ʻia kēia mau polymers i nā ʻano hana ʻoihana like ʻole, me ke ʻano he thickeners, crosslinkers, a i ʻole i ka hoʻomohala ʻana i nā resins kūikawā.

ʻAcrylamide Diacetone(DAAM) Mea hoʻolako a me ka hale hana

ʻAcrylamida diacetone(DAAM) he hui organik versatile i hoʻohana nui ʻia i ka ʻepekema polymer, ʻenehana uhi, a me ka ʻepekema mea. He monomer synthetic ia i loaʻa ka nānā nui ma muli o kona mau waiwai kemika kū hoʻokahi, e like me ke kiʻekiʻe o ka reactivity, ka hiki ke hana i nā ʻano polymer like ʻole, a me ka hiki no nā noi hana like ʻole. He kuleana koʻikoʻi ko DAAM i ka hoʻomaikaʻi ʻana i nā waiwai o nā polymers, nā uhi, nā mea hoʻopili, a me nā composites.

1. ʻAno Kemika a me nā Waiwai o Diacetone Acrylamide

ʻO ka Diacetone acrylamide kahi derivative acrylamide, kahi i pani ʻia ai ka hui acrylamide e kahi ʻāpana acetone ma ke kūlana nitrogen. ʻO ke ʻano kemika o DAAM ʻo iaC₆H₁₁NO₂, a ʻo kona kaumaha molekala ma kahi o129.17 g/mol.

ʻO ke ʻano o DAAM:

An hui acrylamide(CH₂=CH-C(=O)-NH-), ʻo ia ka ʻāpana hana nui o ka molekala.
A hui diacetone(C₄H₇O₂), ka mea i hoʻopili ʻia i ka naikokene o ka acrylamide.

Nā Hiʻohiʻona

Hoʻopili maʻalahi ka diacetone acrylamide a hana i nā copolymers me nā ʻano comonomers like ʻole.
Hoʻopili ka Diacetone acrylamide me ka hui ketone o ka adipic acid dihydrazide ma ka mahana maʻamau.

ʻO ke alo o kahui hana acrylamidee hiki ai iā DAAM ke polymerize ma ke ʻano like me nā mea ʻē aʻenā monomers i hoʻokumu ʻia i ka acrylamide, ʻoiai ʻo kaʻano diacetonehāʻawi i kahi keʻakeʻa steric e hoʻopilikia ai i kona reactivity a me nā waiwai kino. Hoʻolilo pū ka hui acetone i ka hui i mea hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik.

2. Hana ʻia ʻana o ka Diacetone Acrylamide

ʻO ka hana ʻana o DAAM e pili ana i kahi kaʻina hana ʻelua-ʻanuʻu:

Ka hoʻohuihui ʻana o ka acrylamideʻO kēia hana mua e pili ana i ka hoʻopili ʻana i ka acrylamide me ka acetone i ke alo o kahi mea hoʻoulu waikawa a kumu paha. Hoʻopili ka acetone me ka ʻātoma nitrogen o ka acrylamide e hana i ka diacetone derivative.
Hoʻomaʻemaʻe ʻanaKe pau ka hopena, hoʻomaʻemaʻe pinepine ʻia ka huahana ma o nā ʻano hana distillation a i ʻole crystallization e hoʻokaʻawale i kaMonomer DAAMma kona ʻano maʻemaʻe.

Hiki ke wehewehe ʻia ka hopena penei:

ʻAkrilamida (CH₂=CH-C(=O)-NH₂)hana me ka acetone (CH₃COCH₃) e hana i ka diacetone acrylamide (CH₂=CH-C(=O)-NH-CH₂COCH₃).

He maʻalahi ka hana ʻana o DAAM, akā pono ka kaohi pololei ʻana i nā kūlana hopena (e laʻa, ka mahana, ka manawa hopena, ke koho ʻana o ka mea hoʻoheheʻe) e hoʻokō ai i nā hua kiʻekiʻe a me ka maʻemaʻe.

3. Polymerization o Diacetone Acrylamide

ʻO ka hiʻohiʻona koʻikoʻi o DAAM ʻo ia kona hiki ke hoʻololi i ke ʻanoka polymerization radical manuahiHiki i ka hui acrylamide ma DAAM ke komo i nā hopena polymerization hoʻohui, e ʻae ana iā DAAM e hoʻopili me nā monomers ʻē aʻe a i ʻole ia iho e hana i nā kaulahao polymer lōʻihi. ʻO kēia ka mea e lilo ai ʻo DAAM i monomer pono i ka hana ʻana o nā polymers me nā waiwai like ʻole.

Hiki ke hana ʻia ka polymerization o DAAM ma o:

HomopolymerizationHoʻopili ka monomer DAAM me nā monomers DAAM ʻē aʻe, e hana ana i kahi polymer i haku ʻia me nā ʻāpana DAAM.
Nā CopolymersHiki ke hoʻohui ʻia ʻo DAAM me nā acrylate, methacrylate, a i ʻole nā monomers vinyl e hana i nā copolymers me nā waiwai i hana kūikawā ʻia. ʻAe kēia i ka hoʻohui ʻana o nā hui hana kikoʻī e hāʻawi i nā ʻano kūikawā i ka polymer.

Nā mea hoʻomaka radical manuahi (e.g.,ʻAIBN, BPO) a i ʻole ke kukui UV e hoʻohana pinepine ʻia e hoʻomaka i ke kaʻina hana polymerization. ʻO ka hopenaNā polymers i hoʻokumu ʻia ma DAAMhiki ke loaʻa i kahi ākea o nā waiwai ma muli o ke kekelē o ka polymerization, ke alo o nā mea crosslinking, a me ke ʻano o nā co-monomers i hoʻohana ʻia.
