Kwv yees li 3 lab tons ntawm adipic acid yog tsim txhua xyoo. Txog 10% yog siv rau hauv kev lag luam khoom noj hauv Canada, EU lub teb chaws, Tebchaws Asmeskas thiab ntau lub tebchaws CIS.
Cov khoom noj uas muaj adipic acid:
Cov yam ntxwv ntawm adipic acid
Adipic acid, los yog raws li nws tseem hu ua, hexanedioic acid, yog ib qho E 355 zaub mov ntxiv uas plays lub luag hauj lwm ntawm stabilizer (acidity regulator), acidifier thiab ci hmoov.
Adipic acid yog nyob rau hauv daim ntawv ntawm cov xim tsis muaj kob nrog ib tug qaub saj. Nws yog tsim los ntawm kev sib cuam tshuam ntawm cyclohexane nrog nitric acid lossis nitrogen.
Kev tshawb fawb ntxaws txog tag nrho cov khoom ntawm adipic acid yog tam sim no tab tom ua. Nws tau pom tias cov tshuaj no yog tshuaj lom neeg tsawg. Raws li qhov no, cov kua qaub raug xa mus rau chav kawm kev nyab xeeb thib peb. Raws li Lub Xeev Tus Qauv (hnub tim 12.01, 2005), adipic acid muaj kev phom sij tsawg rau tib neeg.

Ib tug siab concentration ntawm ib yam khoom nkag mus rau hauv lub pa ib ntsuj av tau yuav irritate lub mucous daim nyias nyias.
Ntau cov adipic acid tuaj yeem nkag mus rau hauv lub cev thaum tsim cov polyurethane fibers.
Txhawm rau zam qhov tsis zoo rau kev noj qab haus huv, nws raug nquahu kom ua raws li txhua yam kev tiv thaiv tsim nyog ntawm lub tuam txhab, ua raws li cov qauv kev huv. Qhov siab tshaj plaws tso cai tus nqi ntawm cov ntsiab lus ntawm cov khoom hauv huab cua yog 4 mg rau 1 m3.
Cov cim qhia ntawm adipic acid ntau dhau
Cov ntsiab lus acid nyob rau hauv lub cev tsuas yog tuaj yeem pom los ntawm kev dhau qhov kev ntsuam xyuas tsim nyog. Txawm li cas los xij, ib qho ntawm cov cim qhia ntawm ntau dhau ntawm adipic acid tuaj yeem ua rau tsis muaj teeb meem (piv txwv li, ua xua) khaus ntawm cov mucous ntawm lub qhov muag thiab ua pa.
Tsis pom muaj cov tsos mob ntawm adipic acid deficiency.
Kev sib cuam tshuam ntawm adipic acid nrog lwm cov ntsiab lus:
Adipic acid yooj yim reacts nrog lwm yam kab kawm. Piv txwv li, cov khoom yog heev soluble thiab crystallizes nyob rau hauv dej, ntau yam cawv.
