Encyclopedia of Chemical Raw Materials--O a ituaiga o vailaau mata'utia?

1. E masani ona vaevaeina mea tau vaila'au i ni vaega se lua: vaila'au fa'ama'i fa'ama'i ma mea fa'amea fa'ama'i fa'aletino e tusa ai ma a latou meafaitino.

(1) Mea fa'alekemiki fa'aletino

E mafai ona vaevaeina i alkanes ma a latou mea e maua mai ai, alkenes ma a latou mea e maua mai ai, alkynes ma a latou mea e maua mai ai, quinones, aldehydes, alcohols, ketones, phenols, ethers, anhydride, esters, organic acids, carboxylic acids Salts, carbohydrates, heterocyclics, nitriles, halogenated type , amino amides, ma isi.

(2) O mea fa'a-kemikolo fa'ama'i

O mea autu autu o oloa vailaʻau inorganic o minerale vailaʻau o loʻo i ai le sulfur, sodium, phosphorus, potassium, calcium (silasila i alamanuia masima inorganic) ma koale, suauu, kasa masani, ea, vai, ma isi. le tele o alamanuia vaega o mea mataʻina foi mo vailaau inorganic, e pei o le ogaumu kasa coke i le faagasologa o le gaosiga o coking i le alamanuia uamea. O le amonia o loʻo i totonu e mafai ona toe maua mai i le sulfuric acid e maua ai le ammonium sulfate, chalcopyrite, ma le galena. O le sulfur dioxide i totonu o le kesi otaota faʻafefeteina o maina ma sphalerite e mafai ona faʻaaogaina e gaosia ai le sulfuric acid, ma isi.

2. E tusa ai ma le faagasologa o le gaosiga, e mafai ona vaevaeina i le amataina o mea mataʻutia, mea faʻapitoa ma mea faʻapitoa.

(1) Mea amata

Amata mea mataʻutia o mea mataʻina ia e manaʻomia i le laasaga muamua o le gaosiga o vailaʻau, e pei o le ea, vai, suauʻu faʻasolosolo (e pei o le koale, suauʻu, kasa masani, ma isi), masima o le sami, minerale eseese, mea tau faʻatoʻaga (e pei o le starch- o lo'o i ai fatu po'o laau vao, Laau Cellulose, ofe, ofe, vaomago, ma isi).

(2) Mea mata'utia fa'avae

E maua mai mea fa'apitoa e ala i le fa'againa o mea amata, e pei o le calcium carbide ma 'ese'ese mea fa'aola ma mea fa'aletino o lo'o lisi atu i luga.

(3) O mea mata'utia

E ta'ua fo'i mea fa'ava-o-va'ava'a. E masani ona latou fa'asino i oloa na gaosia mai mea mata'utia i le gaosiga o vaila'au fa'aletino lavelave, ae e le'i o ni oloa mo le fa'aaogaina mulimuli ma e mana'omia ai nisi gaioiga. Mo se faʻataʻitaʻiga, o vailaʻau faʻasolosolo eseese e faʻaaogaina i le gaosiga o vali, palasitika ma vailaʻau: methanol, acetone, vinyl chloride, ma isi.
