Lignin Amine

1. Taw qhia

Lignin yog ib tug complex polymer muab rho tawm los ntawm cov nroj tsuag, uas muaj nyob rau hauv lub cell phab ntsa ntawm yuav luag tag nrho cov terrestrial nroj tsuag. Lignin, uas suav txog 20% ​​mus rau 30% ntawm cov ntoo, yog cov nplaum ntuj thiab viscous. Nws tuaj yeem ua ke cellulose nrog hemicellulose, muab cov ntoo tawv thiab tawv tawv. Qhov no yog cov pa roj carbon monoxide loj tshaj plaws tom qab cellulose.Lignin amines yog tsim los ntawm reacting ib nrab los yog ib tug tertiary amine thiab ib tug halohydrin nrog lignin. Cov amine thiab halohydrin zoo dua tuaj yeem ua ke los ua ib qho glycidylamine nruab nrab. Los ntawm 1-10 moles ntawm glycidylamine intermediate ib 1, 000 grams ntawm lignin yog ces reacted ua ke. Nyob rau hauv kev nyiam embodiments ntawm invention, lub halohydrin yog epichlorohydrin, theem nrab amine yog dimethyl thiab tertiary amine yog trimethyl amine. Cov lignin amines no muaj txiaj ntsig zoo li cov neeg ua haujlwm saum npoo av, tshwj xeeb tshaj yog nyob rau hauv cationic asphalt emulsions.

2. Muaj nuj nqi

Lignin Amine tuaj yeem siv los ua cov txheej txheem qeeb asphalt emulsifier, tshwj xeeb tshaj yog rau cov ntawv thov kev ruaj ntseg. Nws muaj cov cim hauv qab no:

2.1 Zoo cia ruaj khov
2.2 Kev sib xyaw ua haujlwm zoo
2.3 tuaj yeem ua ke nrog kev sib tw thiab kev sib tw ntawm kev sib sau
2.4 Emulsion-rau-tag nrho compatibility

3. Daim ntawv thov

Lignin Amine hmoov yog siv rau hauv kev tsim kho kev lag luam, Kev ua liaj ua teb, thiab kev lag luam.

6. Kev xeem

Cov kauj ruam:

Kev npaj cov hnab lim thiab cov qauv:
1. Siv lub cim ntsuas qhov hnyav los ntsuas lub hnab lim thiab ntsuas nws (m 1).
2. 0.5 g (±{3}}.05 g) cov qauv npaj (m) raug ntsuas ncaj qha thiab raug rau hauv lub hnab lim. Cov qauv yuav tsum tau crushed los ntawm 1 mm sieve.
3. Sib khi nrog lub tshuab sealing txog 5 hli los ntawm ntug sab saud ntawm lub hnab lim. Tom qab ntawd cov qauv yog flattened nyob rau hauv lub hnab lim thiab muab sib npaug.
4. Siv tsawg kawg ib lub hnab lim dej (C1) thiab ua qhov kev txiav txim siab dawb paug tib lub sijhawm.
5. Ua ntej, nws raug kho raws li txoj kev txiav txim siab ADF.
Tom qab ADF txiav txim siab, muab lub hnab lim qhuav / qauv rau hauv 3 L beaker thiab muab tso rau hauv lub hnab lim nrog 72% sulfuric acid (li 250mL).
Ib qho tseem ceeb: lub hnab lim yuav tsum qhuav tag thiab txias rau hauv chav tsev kub ua ntej ntxiv cov concentrated acid. Yog tias muaj cov dej noo hauv lub hnab lim thiab cov cua sov yog tsim tom qab ntxiv sulfuric acid, nws yooj yim rau scorch cov qauv hauv lub hnab thiab cuam tshuam rau kev txiav txim siab.
1. Muab 2 L beaker rau hauv 3 L beaker rau hauv lub hnab lim. Do lub hnab lim thaum pib thiab nqa 2L beaker nce thiab nqis li 30 feeb.
Ib zaug.
Ncuav cov sulfuric acid tom qab 2.3 teev, tom qab ntawd ntxuav nws nrog dej kom tshem tawm cov kua qaub. Rov ntxuav dua kom txog thaum pH nruab nrab. Tom qab ntawd eluted nrog 250 mL acetone rau 3 min tsuas yog.
Tso dej.
3. Qhuav nyob rau hauv ib tug 105 degree qhov cub rau 4 h, ces txias rau chav tsev kub nyob rau hauv lub tshuab ziab khaub ncaws thiab hnyav (m ~ 2).
Tsis txhob muab lub hnab lim tso rau hauv qhov cub kom txog thaum cov acetone tag nrho evaporated.

4. Lub hnab lim tau muab tso rau hauv qhov hnyav (m ~ 3) 30 lossis 50 mL crucible, ashing rau 3 h ntawm 525 degree, txias thiab hnyav

8. Kev ruaj ntseg thiab kev nyab xeeb

Peb tau ua ntau yam kev ruaj ntseg thiab kev nyab xeeb kawm txog cov khoom no, raws li cov ntaub ntawv ceev ceev thiab kev ruaj ntseg mus sij hawm ntev, nws qhia cov yam ntxwv ruaj khov; raws li kev tshawb nrhiav tsiaj txhu, nws qhia tau tias muaj kev nyab xeeb.
