L-Lysine Diisocyanate CAS 45172-15-4

Kono Chem Co., Ltd. yog ib qho zoo tshaj plaws manufacturers thiab lwm tus neeg ntawm l-lysinediisocyanate cas45172-15-4 hauv Suav teb. Peb sov siab txais tos koj rau cov lag luam wholesale bulk l-lysinediisocyanate cas45172-15-4 muag ntawm no los ntawm peb lub hoobkas. Tag nrho cov khoom siv tshuaj muaj txiaj ntsig zoo thiab cov nqi sib tw.

1 Kev Taw Qhia

 Lysine Diisocyanate, 2,6-DisocyanatoEthylCaproate, CAS No. 45172-15-4, nrog cov mis mos molecular C10H14N2O4, zoo li cov kua daj daj rau daj oily ntawm chav tsev kub, feem ntau muaj cov ntsiab lus ntawm 95%

2 Muaj nuj nqi thiab kev siv

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 coatings, uas muaj nqi thov. Kev tshawb fawb tau pom tias LDI tuaj yeem txhim kho cov dej tsis kam, lub zog tensile, thiab cov khoom sib txuas ntawm polylactic acid (PLA), xyoob fiber ntau (BF), thiab polybutylene succinate (PBC) cov ntaub ntawv sib xyaw. Cov txiaj ntsig tseem ceeb tau raug 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.

4 Chromatogram

5 Flow Chart

Kauj ruam 1: Synthesis ntawm L-lysine ethyl ester hydrochloride: Lysine yog yaj nyob rau hauv anhydrous ethanol, hydrogen chloride gas yog qhia, rhuab thiab refluxed rau li 1 teev, txias, thiab ces anhydrous ether yog ntxiv dropwise rau precipitate cov khoom. Cov khoom nyoos ntawm lysine ethyl ester hydrochloride yog tau los ntawm kev ntxuav thiab ziab, nrog cov txiaj ntsig ntawm kwv yees li 85%.
Kauj Ruam 2: Cov tshuaj tiv thaiv nrog Triphosgene: Sib tov lysine ethyl ester hydrochloride, Triphosgene, thiab thawj cov organic hnyav (xws li dichloromethane), thiab tom qab ntawd ntxiv cov organic hauv paus (xws li pyridine) dropwise rau cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv kub yog tswj ntawm 10℃-25 degree.
Kauj Ruam 3: Lim thiab Concentration: Tom qab cov tshuaj tiv thaiv tiav, lim kom tshem tawm cov organic hauv paus hydrochloride ntsev, mloog zoo rau cov filtrate kom rov qab tau cov kuab tshuaj, ntxiv ib qho thib ob organic hnyav (xws li toluene) kom precipitate cov ntsev seem, lim dua thiab mloog zoo nyob rau hauv lub siab txo kom tau cov khoom crude.
Kauj Ruam 4: Refining thiab Purification: Cov khoom nyoos yog sau los ntawm molecular distillation (kub 125℃-145 degree, nqus tsev kawm ntawv 10Pa -400Pa) kom tau txais cov khoom ua kua daj daj nrog lub purity ntawm ntau dua 99%. cov
