Lanthhanum chloride heptahydrate 丨 cas 10025-84-0

1. CATALYENYY thiab organic synthesis

Lanthhanum chloride yog dav siv ua lewis acid catalyst hauv cov organic cov tshuaj tiv thaiv:

Aldol Cov Khaub Ncaws, Michael Ntxiv, Micaiyama Aldol Cov Kev Nqis

Friedel-crafts acylations / alkylations

Diels-alder

Nws muaj cov kev xaiv siab thiab ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov kev hloov pauv kom muaj zog acidic tej yam kev mob. Tus kab mob tau zoo tshaj plaws yog cov nyiam rau aqueous-theem cov tshuaj tiv thaiv thiab tuav.

2. Khoom siv science thiab ceramics

Lanthalhanum tebchaw yog qhov tseem ceeb hauv kev ua cov ntaub ntawv siab heev:

Siv nyob rau hauv synthesis raws li cov pakthancites (piv txwv li, lifeo₃, Lamnoo₃), uas yog qhov tseem ceeb hauv:

Cov roj oxide roj hlwb (sofcs)

Catalytic convers

Dielectric ntaub ntawv

Ua raws li dopant nyob rau hauv cov ntaub ntawv kho qhov muag, superconductors, thiab cov ceramic ceramitors.

3. Dej Kho

Phosphate Remover:
Lanthalhanum chloride yog siv los nag hauv phosphate hauv:

Kev tso thoob dej yug ntses (REAF tso tsheb hlau luam, cov tso tsheb hlau luam tshiab)

Ua luam dej pas

Cov Kev Kho Kom Qhuav Tshuab

Txoj kev ua si ntawm cov suab nrov nrog phosphate los ua insoluble lanthanum phosphate, uas tau yooj yim ferted lossis hais tawm algae kev loj hlob thiab eutrophication txaus ntshai.

4. Biomedical thiab analytical chemistry

Kev tshawb fawb ntawm kev soj ntsuam cov chelates thiab cov neeg sawv cev:
Lanthhant tau kawm hauv roj ntsha, MRI sib txawv cov neeg sawv cev, thiab kev tshawb nrhiav kev kho kev kho mob.

Analytical reagent:
Siv hauv Ion-xaiv electrode kev loj hlob thiab spectroscopy (icp-oes, icp-ms) raws li ib tug qauv matrix lossis cov qauv ntsuas hluav taws xob.

5. Cov ntawv thov optical

Lanthhanum chloride yog ib tug ua ntej rau siab-refrathare-index tsom iav, siv nyob rau hauv:

Lub Koob Yees Duab Ntsej Muag

Cov Ntsuas Hluav Taws Xob

Laser tshuab

Cov tsom iav no nthuav qhia cov kev tshem tawm qis dua thiab txhim kho transparency, tshwj xeeb tshaj yog nyob hauv UV-pom thaj chaw.

1. Kev ua siab zoo thiab kev ua tau zoo

Ua txhaum ua mob me thiab zoo li qub cov kua qaub, haum rau noo noo-rhiab thiab cov kuab tshuaj ib puag ncig.

Ua rau cov qoob loo siab thiab xaiv tau hauv cov kev hloov pauv cov organic, feem ntau raws li cov mob me.

2. Ib puag ncig cov nqi hluav taws xob

Raws li phosphate-khi tus neeg sawv cev, lanthhanum chloride heptahydrate:

Pab tiv thaiv kom tsis txhob muaj eutrophication hauv lub cev dej.

Muab cov tshuaj tsis muaj tshuaj lom rau cov tshuaj kho ib txwm muaj nyob rau hauv aquaculture thiab cov dej.

3. Versatile precursor ua ntej rau cov ntaub ntawv siab heev

Qhov tseem ceeb hauv synthesizing ua haujlwm oxides, ceramics, thiab cov khoom siv hluav taws xob.

Kev txhim kho cov khoom zoo li thermal stability, ionic conductivity, thiab cov cwj pwm sib nqus thaum siv nyob rau hauv cov ntaub ntawv sib xyaw.

4. Solubility thiab tuav cov txiaj ntsig zoo

Daim foos HEPTAHDRate yooj yim dua kom yaj, khw, thiab siv piv rau daim ntawv anhydrous.

Muaj kev ruaj khov nyob rau hauv cov xwm txheej zoo, ua kom haum rau kev kuaj thiab kev lag luam siv.

5. Kev sib raug zoo nrog cov xov xwm

Raws li ib feem ntawm cov lus qhia ntawm cov lus qhia ntawm cov lus qhia ntawm lub hauv paus lub luag haujlwm hauv kev tshawb fawb thoob ntiaj teb, tshwj xeeb hauv kev sib koom ua ke kev sib koom ua ke.
