Cov tshuaj yog txhua qhov sib xyaw ua ke uas tsim los ntawm cov txheej txheem tshuaj lom neeg hauv chav kuaj lossis kev lag luam.Lawv tuaj yeem yog cov tshuaj dawb huv lossis sib xyaw ntawm cov tshuaj.Txawm hais tias sib txawv txhais tau hais tias lo lus "chemical" piav qhia tag nrho cov tshuaj thiab lawv cov tebchaw.Txawm li cas los xij, ntawm no, cov tshuaj yuav tsum tsuas yog nkag siab tias yog cov tshuaj lom neeg uas koom nrog cov tshuaj tiv thaiv.
Cov tshuaj tau muab faib ua cov tshuaj organic thiab cov tshuaj inorganic.Organic chemistry npog yuav luag txhua qhov sib txuas uas muaj cov pa roj carbon monoxide, thaum inorganic chemistry (inorganic) cuam tshuam nrog lwm cov ntsiab lus hauv lub rooj zaum thiab lawv cov tebchaw.Petrochemical yog ib ceg ntawm cov organic chemistry.Petrochemicals yog cov khoom siv tshuaj los ntawm cov roj crude thiab cov nkev ntuj.Cov tshuaj no yog muab rho tawm thaum lub sij hawm refining txheej txheem thaum cov roj crude los yog natural gas distilled los yog tawg.
Purity plays lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj, qhov kev sib txawv ntawm cov tshuaj siv tshuaj (tsawg purity) thiab tshuaj zoo (siab purity).Kev lag luam chemicals, tseem hu ua cov tshuaj hnyav, xa mus rau qib inorganic thiab organic cov tshuaj lom neeg yooj yim (xws li sodium hydroxide, sulfuric acid, lossis ethylene) uas tau tsim ntau ntau.Cov tshuaj hnyav no, tseem hu ua cov tshuaj hauv paus lossis cov tshuaj siv hauv paus, yog qhov tsis sib xws rau cov tshuaj zoo purity uas tsim hauv cov khoom me me.Cov yav tas yog siv los ua raw cov ntaub ntawv rau kev kuaj tshuaj synthesis, zaub mov additives los yog tshuaj ntau lawm.
Tsis tas li ntawd, cov tshuaj muaj peev xwm ua rau muaj kev sib txawv thaum lawv sib cuag nrog ib leeg.Chemical compatibility Hloov los yog tsis tov txhua, lawv suav hais tias tau sib xws.suav tias yog incompatible.Yog li ntawd, kev khaws cia thiab tuav cov tshuaj nyob rau hauv tib qhov chaw yuav tsum tau saib xyuas ntxiv thiab ua tib zoo saib xyuas kom tsis txhob muaj cov tshuaj tiv thaiv kab mob.Txoj cai tseem ceeb tshaj plaws yog khaws cov ntaub ntawv tsis sib xws, uas tuaj yeem ua rau hluav taws, tawg, lossis tsim cov pa phem yog tias sib xyaw ua ke.Raws li txoj cai dav dav, cov tshuaj tsis sib xws yuav tsum tau muab khaws cia rau hauv lub tank cais.Cov hub yuav tsum tau cim kom meej nrog cov khoom khaws cia hauv lawv.
