Encyclopedia of Chemical Raw Materials - Mefuta ea lisebelisoa tsa lik'hemik'hale ke efe?

1. Lisebelisoa tsa lik'hemik'hale ka kakaretso li ka aroloa ka mekhahlelo e 'meli: lisebelisoa tse tala tsa lik'hemik'hale tsa tlhaho le lisebelisoa tsa lik'hemik'hale tsa lik'hemik'hale ho latela mehloli ea tsona.

(1) Lintho tse tala tsa lik'hemik'hale

E ka aroloa ka li-alkanes le lihlahisoa tsa tsona, alkenes le lihlahisoa tsa tsona, alkynes le lihlahisoa tsa tsona, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydrides, esters, organic acids, carboxylic acid Letsoai, lik'habohaedreite, heterocyclics, mefuta ea halogen halogen, li-amino amide, joalo-joalo.

(2) Lintho tse tala tsa lik'hemik'hale

Thepa e ka sehloohong ea lihlahisoa tsa lik'hemik'hale tsa lik'hemik'hale ke liminerale tsa lik'hemik'hale tse nang le sebabole, sodium, phosphorus, potasiamo, k'halsiamo (bona indasteri ea letsoai ea inorganic) le mashala, oli, khase ea tlhaho, moea, metsi, joalo-joalo Ho phaella moo, lihlahisoa le litšila mafapha a mangata a indasteri le tsona ke lisebelisoa tse tala bakeng sa lik'hemik'hale tse sa sebetseng, joalo ka khase ea oveni ea coke ts'ebetsong ea tlhahiso ea coking indastering ea tšepe. Ammonia e ka ho eona e ka fumanoa ka sulfuric acid ho hlahisa ammonium sulfate, chalcopyrite, le galena. Sulfur dioxide e ka har'a khase ea litšila e qhibilihang ea merafong le sphalerite e ka sebelisoa ho hlahisa sulfuric acid, joalo-joalo.

2. Ho ea ka ts'ebetso ea tlhahiso, e ka aroloa ka ho qala lisebelisoa tse tala, lisebelisoa tsa motheo tsa lihlahisoa le lihlahisoa tsa bohareng.

(1) Lisebelisoa tsa ho qala

Ho qala lisebelisoa tse tala ke lisebelisoa tse tala tse hlokahalang mohatong oa pele oa tlhahiso ea lik'hemik'hale, joalo ka moea, metsi, mafura a khale (ke hore, mashala, oli, khase ea tlhaho, joalo-joalo), letsoai la leoatle, liminerale tse fapaneng, lihlahisoa tsa temo (tse kang starch- e nang le lijo-thollo kapa limela tse hlaha, lehong la Cellulose, bamboo, lehlaka, joang, joalo-joalo).

(2)Lisebelisuoa tsa motheo tse tala

Lisebelisoa tsa mantlha tse tala li fumanoa ka ho lokisa lisebelisoa tsa ho qala, joalo ka calcium carbide le lisebelisoa tse fapaneng tsa tlhaho le tsa inorganic tse thathamisitsoeng kaholimo.

(3) Lisebelisoa tse tala tsa lipakeng

Lisebelisoa tse tala tsa lipakeng li boetse li bitsoa intermediates. Ka kakaretso li bua ka lihlahisoa tse hlahisoang ka thepa ea mantlha ea tlhahiso ea lik'hemik'hale tse rarahaneng, empa ha e e-so be lihlahisoa bakeng sa ts'ebeliso ea ho qetela mme li hloka ts'ebetso e eketsehileng. Ka mohlala, metsoako e fapa-fapaneng ea lintho tse phelang e sebelisoang ho hlahisa lidae, polasetiki le meriana: methanol, acetone, vinyl chloride, joalo-joalo.
