Peb sov siab txais tos koj rau cov lag luam wholesale bulk cas 45172-15-4 l-lysine diisocyanate muag ntawm no los ntawm peb lub hoobkas. Tag nrho cov khoom siv tshuaj muaj txiaj ntsig zoo thiab cov nqi sib tw.

1. Taw qhia

L-Lysine diisocyanate (LDI), tseem hu ua L-Lysine diisocyanate, yog cov organic compound. Nws cov npe lus Askiv muaj xws li L-Lysine Diisocyanates, 2,6-DisocyanatoEthylCaproate, thiab lwm yam. Nws tus lej CAS yog 45172-15-4, nws cov mis molecular yog C10H14N2O4, thiab nws zoo nkaus li daj me ntsis rau daj oily kua nyob rau hauv chav tsev kub, nrog 95%.

Cov tshuaj no tsuas yog siv los ua cov khoom siv tshuaj lom neeg hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov polyurethane txheej. Kev tshawb fawb tau pom tias LDI tuaj yeem txhim kho cov dej tsis kam, lub zog tensile thiab kev sib txuas ntawm cov khoom ntawm polylactic acid (PLA), xyoob fiber ntau (BF) thiab polybutylene succinate (PBC) composites. Cov txiaj ntsig tseem ceeb tau tshaj tawm hauv kev tshawb fawb txawv teb chaws. Nws cov qauv molecular muaj cov pab pawg isocyanate, muab cov chaw ua haujlwm rau tshuaj lom neeg.

2. Muaj nuj nqi

Tus nqi tseem ceeb ntawm L-Lysine diisocyanate yog tias nws hloov cov roj av ib txwm siv- muab cov khoom noj nrog L-Lysine thiab yog li pom tias yog qhov kev xaiv zoo dua qub thiab ib puag ncig zoo. Nws cov ntawv thov tseem ceeb tau cuam tshuam hauv cov hauv qab no:

2.1 Kev npaj biobased polyurethane: Qhov no yog daim ntawv thov tseem ceeb ntawm LDI. Nws muaj ob pawg isocyanate reactive heev (-N=C=O) thiab tuaj yeem cuam tshuam nrog polyols los ua cov ntaub ntawv biobased polyurethane. Cov khoom no yog nrov nyob rau hauv cov nram no:

Biomedicine: Siv los tsim cov cuab yeej kho mob, cov ntaub so ntswg engineering scaffolds, cov tshuaj tiv thaiv kev tso tawm, thiab lwm yam uas muaj kev nyab xeeb dua rau tib neeg lub cev.

2.2 Cov Khoom Siv Khoom Siv: Siv rau hauv kev tsim khoom ntawm ib puag ncig tus phooj ywg textiles, foam plastics, coatings thiab adhesives.

Raws li kev hloov pauv ntawm cov ntaub ntawv polymer: LDI tuaj yeem siv los ua "compatibilizer" lossis "coupling agent" los txhim kho lub zog sib txuas ntawm cov khoom sib txawv. Cov kev tshawb fawb tau pom tias nws tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv hauv qab no:

Txhim kho dej tsis kam: Txo cov khoom nqus dej.

Txhim khu lub zog tensile: Ua kom cov khoom muaj zog thiab ruaj khov dua.

Txhim kho kev sib txuas ntawm kev sib txuas: Ua kom cov khoom sib txawv khi ze dua.

Piv txwv li, nws tuaj yeem siv los txhim kho cov khoom zoo ntawm biomass composites xws li polylactic acid (PLA) / xyoob fiber (BF).

2.3 Raws li cov organic synthesis nruab nrab: Ua tsaug rau cov qauv ntawm nws cov amino acid derivatives thiab reactive isocyanate pawg, LDI kuj tseem siv tau los ua ib qho tseem ceeb nruab nrab rau cov synthesis ntawm ntau complex compounds, xws li rau kev npaj ntawm polypeptides los yog synthesis ntawm lwm yam tshuaj zoo.

3. Daim ntawv thov

L-Lysine diisocyanate yog siv dav hauv kev lag luam, mainly siv nyob rau hauv kev lag luam rau polyurethane txheej ntau lawm

5.Txoj kev tsom xam

Tshuaj titration-di-n-butylamine method

Qhov no yog cov txheej txheem classic thiab feem ntau rau kev txiav txim siab cov ntsiab lus isocyanate (cov qauv siv xws li ASTM D2572 lossis HG / T 2409). Haum rau nruab nrab tswj kev kuaj ntawm LDI crude khoom thiab cov txheej txheem polymerization.

Lub hauv paus ntsiab lus: Cov pab pawg isocyanate (-NCO) hauv LDI reacts nrog ntau dhau di-n-butylamine los ua urea. Tom qab cov tshuaj tiv thaiv tiav lawm, qhov seem di-n-butylamine yog titrated nrog cov txheej txheem hydrochloric acid tov.

R-NCO+(C4​H9​)2NH →R-NHCON(C4​H9​)2​

(C4​H9​)2​NH(Seem) + HCl →(C4​H9​)2NH⋅HCl

Cov lus piav qhia luv luv ntawm cov kauj ruam ua haujlwm:

Ua kom hnyav ib qho piv txwv ntawm LDI thiab yaj nws hauv anhydrous toluene (los yog acetone).

Ntxiv qhov ntim ntawm di-n-butylene-toluene standard tov.

Cov tshuaj tiv thaiv ntawm chav tsev kub rau ib lub sijhawm (feem ntau 15-30 feeb).

Ntxiv bromophenol xiav (los yog isopropanol) ua qhov taw qhia.

Titrate nrog hydrochloric acid txheem tov rau daj kawg.

Nyob rau tib lub sijhawm, kev sim dawb tau ua.
