Nnuru a Wɔde Yɛ Adwuma: Sɛ́ dicarboxylic acid no, adipic acid kura carboxyl dwumadi akuw abien (-COOH), a ɛma ɛyɛ nnuru a ɛyɛ adwuma kɛse. Ɛde ne ho hyɛ esterification reactions a ɛne nsa yɛ mu ntɛm ara, na ɛyɛ esters a wɔde di dwuma kɛse wɔ plastic, srade, ne huam a wɔyɛ mu. Bio nso, ebetumi ne diamines ayɛ adwuma denam condensation polymerization so ayɛ polyamides, titiriw nylon 6,6. Saa polymerization adeyɛ yi yɛ tweatibo a ɛwɔ synthetic fiber ne engineering plastics nnwuma mu. Adipic acid nso tumi fa reduction reactions mu ma ɛyɛ alcohols a ɛne no hyia na ebetumi ne bases ayɛ adwuma ayɛ nkyene, a wɔfrɛ no adipates.

Mmeae a Wɔde Di Dwuma

Polyamide (Nylon) a Wɔyɛ: Adipic acid a wɔde di dwuma kɛse na ɛho hia sen biara no gyina polyamides a wɔyɛ, titiriw nylon 6,6. Wɔ saa adeyɛ yi mu no, adipic acid ne hexamethylenediamine yɛ adwuma wɔ condensation polymerization adeyɛ mu. Nylon 6,6 a efi mu ba no yɛ mfiridwuma mu plastic a ɛyɛ adwuma yiye a agye din wɔ n’ahoɔden, ɛkyɛ, ɛko tia akisikuru, ne mfiri a ɛkyɛn so. Wɔde Nylon 6,6 di dwuma kɛse wɔ kar adwumayɛ mu ma nneɛma te sɛ engine afã horow, gya ahorow, ne bearing ahorow. Ɛsan nso yɛ ade titiriw wɔ ntama adwumayɛ mu, baabi a wɔde yɛ ntama a ɛkorɔn a wɔde yɛ ntade, kapet, ne nneɛma a wɔde siesie nneɛma esiane n’ahoɔden, ahoɔden a ɛyɛ den, ne tumi a ɛkura nnuru a wɔde yɛ nneɛma yiye nti.

Nneɛma a Wɔde Yɛ Plasticizer ne Srade: Wɔde adipic acid yɛ plasticizers a egyina adipate - so. Wɔde saa plasticizers yi ka polymers ho, titiriw polyvinyl chloride (PVC), na ama wɔatumi ayɛ nsakrae, wotumi yɛ ho adwuma, na ɛyɛ den. Wɔpɛ adipate plasticizers wɔ mmeae a ɛho hia sɛ wɔyɛ nsakrae wɔ ɔhyew a ɛba fam mu, te sɛ nea wɔyɛ wɔ kar nhama a wɔde siw ano, aduruyɛ mu nsukorade, ne PVC nneɛma a ɛko tia awɔw mu. Bio nso, wɔde esters a wonya fi adipic acid mu di dwuma sɛ srade wɔ mfiridwuma mu nneɛma ahorow mu, na ɛma ahoɔden a eye kyɛn so a ɛko tia - wear ne anti - friction, na ɛfata sɛ wɔde di dwuma wɔ engine, gear, ne mfiridwuma nhyehyɛe afoforo mu.

Aduan ne Nsã Ho Nnwuma (Wɔde Di Dwuma a Ɛnteɛ): Bere a wɔmfa adipic acid nni dwuma tẽẽ wɔ aduan mu no, wɔde di dwuma wɔ nneɛma a wɔde di dwuma wɔ aduan mu ne nnwinnade a wɔde yɛ aduan mu. Ne esters, sɛ wɔde di dwuma wɔ coatings ne sealants a wɔde yɛ aduan - nneɛma a wɔde kyekyere nneɛma ho a, ɛboa ma wɔhwɛ ma nnuan mu nneɛma yɛ pɛpɛɛpɛ na ahobammɔ wom denam efĩ a esiw ano na ɛma nneɛma no yɛ foforo no so.

Cyclohexane a ɛyɛ oxidation: Eyi ne ɔkwan titiriw a wɔfa so yɛ adipic acid wɔ mfiridwuma mu. Adeyɛ no fi ase denam cyclohexane a ɛyɛ oxidation wɔ catalyst anim, mpɛn pii no ɛyɛ cobalt - based catalyst. Wɔ oxidation a edi kan - fã no mu no, cyclohexane ne mframa anaa oxygen yɛ adwuma ma ɛyɛ cyclohexanol ne cyclohexanone afrafra, adeyɛ a wonim no sɛ "KA ngo" (ketone - nsa ngo) adeyɛ. Wɔyɛ adeyɛ no wɔ ɔhyew a ɛyɛ bɛyɛ 150 - 160°C ne nhyɛso a ɛyɛ 1 - 1.5 MPa. Akyiri yi, wɔsan yɛ KA ngo no oxidized wɔ second - stage reaction a wɔde nitric acid di dwuma sɛ oxidizing agent, mpɛn pii no wɔ ɔhyew a ɛyɛ 60 - 80°C ne wim nhyɛso mu. Saa oxidation a ɛtɔ so mmienu yi dane cyclohexanol ne cyclohexanone ma ɛbɛyɛ adipic acid. Nanso, saa kwan yi wɔ nneɛma a atwa yɛn ho ahyia ho nsɛnnennen bi, efisɛ nitric acid a wɔde di dwuma no ma wonya nitrous oxide (N2O), mframa a ano yɛ den a ɛma wim yɛ hyew, na ɛhwehwɛ sɛ wɔhwɛ nwura a ɛkɔ so no yiye.
