Cov khoom siv tshuaj lom neeg feem ntau tuaj yeem muab faib ua ob pawg tseem ceeb: cov khoom siv tshuaj organic thiab cov khoom siv tshuaj inorganic.
Organic chemical raw cov ntaub ntawv tuaj yeem muab faib ua alkanes thiab lawv cov derivatives, alkenes thiab lawv cov derivatives, alkynes thiab lawv cov derivatives, quinones, aldehydes, cawv, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylates, liccogens, compounds, heterochalate. aminoacyl compounds, thiab lwm yam.
Inorganic chemical raw cov ntaub ntawv yog tsim los ntawm chemical minerals uas muaj sulfur, sodium, phosphorus, potassium, calcium, thiab lwm yam (saib Inorganic Salt Industry), nrog rau cov thee, roj av, natural gas, cua, thiab dej. Tsis tas li ntawd, ntau cov khoom lag luam thiab cov khoom pov tseg los ntawm ntau qhov chaw lag luam kuj yog cov khoom siv raw rau cov tshuaj inorganic. Piv txwv li, cov ammonia muaj nyob rau hauv coke cub roj los ntawm cov txheej txheem coking nyob rau hauv cov hlau thiab steel kev lag luam yuav rov qab tau siv sulfuric acid los tsim ammonium sulfate; sulfur dioxide nyob rau hauv smelting khib nyiab roj los ntawm chalcopyrite, galena, thiab sphalerite yuav siv tau los tsim sulfuric acid, thiab lwm yam.
