99% n {- hexane
1. Cov yam ntxwv yooj yim ntawm 99% n- hexane
N {- hexane (n {lexane hydrocarbon nrog ib qho ncaj ncees}}}}} dua} dua} High-purity n-hexane ua lub luag haujlwm tseem ceeb hauv kev lag luam thiab kuaj cov ntawv thov. Nws cov yam ntxwv tseem ceeb muaj xws li:
Cov Khoom Siv Lub Cev: Tsis muaj xim thiab pob tshab kua nrog me ntsis roj av "
Tshuaj lom neeg cov khoom: Insoluble hauv dej, tab sis ua kom muaj zog nrog ethanic, thiab chloroform, nrog cov tshuaj lom neeg zoo, tab sis tuaj yeem rhuav tshem hauv qab qhov kub thiab txias.
Cov yam ntxwv kev nyab xeeb: nws yuav tsum tau sau tseg tias nws yog volatile heev, thiab nws vapor thiab huab cua tuaj yeem tsim qhov sib xyaw tawg (tawg txwv tsis pub 1.2 3}} 7.5%). Kev tiv tauj ntev yuav ua rau muaj kev puas tsuaj rau lub paj hlwb thiab yuav tsum tau tiv thaiv nruj.
2. Daim ntawv thov tseem ceeb ntawm 99% n- hexane
1. Kev muaj cov kuab tshuaj (ntawv thov tseem ceeb)
Kev cog roj teeb tawm: Extraction cov roj zaub xws li taum pauv thiab rapeseed, vim yog nws cov kuab tshuaj uas tau nyiam, tau dhau los ua cov kuab tshuaj uas nyiam tshaj plaws hauv cov roj thiab roj kev lag luam.
Roj Hmab Thiab Adhesive Kev Lag Luam: Siv rau degreesing roj hmab khoom, diluting kua nplaum thiab ua cov pvc yasievers.
Pleev xim thiab number case: Raws li ib tug duruent, nws txhim kho cov fluidity thiab ziab nrawm ntawm cov xim tha xim.
2. Tshuaj thiab Kuaj
Kws Kev Lag Luam: Siv Tshuaj Khoom Siv Tshuaj Lom Zem, Kev Siv Hluav Taws Xob Nruab Nrab thiab Kuaj Extraction.
Chromatographic tsom xam: mobile theem lossis kev ua kom huv huv hauv HPLC (kev ua kom muaj zog ua kua chromatography) thiab GC (roj roj chromatography).
3. Lwm cov ntawv thov
Kev lag luam hluav taws xob: Siv rau kev kho cov twj paj nruag ntxuav, xws li cov semiconductors thiab Circuit Court board rho tawm.
Cov tshuaj tiv thaiv polymerization: cov kuab tshuaj lossis tshuaj tiv thaiv me rau qee cov txheej txheem polymerization.
