Iyini i-Tetradecanedioic acid CAS 821-38-5?

I-Tetradecanedioic acid iyinhlanganisela ye-carboxylic acid esetshenziswa njengento eluhlaza ekuhlanganiseni i-lubricant esebenza kahle kakhulu ye-carbon chain diacid diesters enezidingo ezikhethekile zokusebenza. Iphinde isetshenziselwe ukukhiqiza ukusebenza okuphezulu kwe-polyamide eshisayo encibilikisa i-polymerization monomers enamathelayo futhi njenge-monomer ye-polymerization, isabela ngama-diamine ukuze yakhe inayiloni ye-carbon chain ende.

Isicelo

I-Tetradecanedioic acid iyinhlanganisela ye-carboxylic acid esetshenziswa kakhulu ekuhlanganiseni amakha, amapulasitiki wobunjiniyela asezingeni eliphezulu njengenayiloni 1414, izinto zokunamathisela ezincibilikayo ezishisayo, kanye nezingubo zokugqoka. I-Tetradecanedioic acid, njenge-condensation monomer, ihlangana ne-diamine ukuze ihlanganise inayiloni yeketango lekhabhoni ende, ikakhulukazi inayiloni 1314, inayiloni 1414, neyiloni 614.
