Ntawm no, los ntawm cov kev xaiv muab Nylon-6, 6 yog cov polymer uas muaj kev sib txuas ntawm amide. Yog li, nylons tseem hu ua polyamides vim lawv cov yam ntxwv amide pawg hauv cov pob txha caj qaum. Amide pawg nyob rau hauv nylon molecules yog heev polar, thiab tsim hydrogen bonding ib leeg.
Puas nylon 6 puas muaj kev sib txuas?
Nylon 6 yog tsim los ntawm lub nplhaib-qhib polymerization ntawm caprolactam. Caprolactam muaj 6 carbons, li no Nylon 6. … Tsis zoo li nylon 6, 6, nyob rau hauv uas cov kev taw qhia ntawm amide daim ntawv cog lus reverses ntawm txhua daim ntawv cog lus, tag nrho cov nylon 6 amide bonds nyob rau hauv tib txoj kev(saib daim duab: nco ntsoov N rau C kev taw qhia ntawm txhua daim ntawv cog lus amide).
Yuav ua li cas hauv qab no yog amide linkage?
Amides yog qhov nthuav dav hauv qhov xwm txheej thiab thev naus laus zis. Cov proteins thiab cov yas tseem ceeb xws li Nylons, Aramid, Twaron, thiab Kevlar yog cov khoom siv polymers uas nws cov chav sib txuas los ntawm cov pab pawg amide (polyamides); cov kev sib txuas no tau yooj yim tsim, ua kom muaj kev nruj, thiab tiv thaiv hydrolysis.
Puas nylon puas muaj kev sib txuas ntawm amide?
Nylon-6 yog tsim los ntawm monomer hu ua caprolactam. Daim ntawv ceeb toom tias qhov no twb muaj ib qhov txuas. Thaum no molecule polymerizes, lub nplhaib ope ns, thiab cov molecules koom nyob rau hauv ib tug nruam saw.
Puas yog Dacron muaj kev sib txuas hauv nruab nrab?
Raws li koj tau pom hauv daim duab saum toj no, Dacron cov ntaub ntawv ester linkage Nws tseem hu ua Terylene. … Thaum cov carboxylic acid thiab ib qho cawv ua rau, cov dej molecule raug tshem tawm, thiab cov ester molecule raug tsim. Vim tias qhov kev tsim ester no, daim ntawv cog lus no raug xa mus rau kev sib txuas ester.
