1.Nthawi zambiri amagwiritsidwa ntchito poyesa ma reagents, omwe amagwiritsidwa ntchito kwambiri popanga neutralization kapena acidification.Non-amadzimadzi titration solvents, kukonzekera buffer solutions, organic synthesis.Kupanga inki, mankhwala, ulusi wa acetate, acetyl mankhwala, etc. Amagwiritsidwanso ntchito kupasuka phosphorous, sulfure, hydrohalic acid, etc. Monga wowawasa wothandizira, angagwiritsidwe ntchito ngati pawiri zokometsera, kukonzekera viniga, zamzitini chakudya, odzola. ndi tchizi, ndikuzigwiritsa ntchito moyenerera malinga ndi zosowa za kupanga.Itha kugwiritsidwanso ntchito ngati chowonjezera kukoma kwa mowa wa koji, ndipo kuchuluka kwake ndi 0.1-0.3g/kg.Amagwiritsidwa ntchito ngati zosungunulira popanga mphira, mapulasitiki, utoto, etc. Amagwiritsidwanso ntchito ngati zopangira kupanga vinilu acetate, mapadi acetate, menthyl acetate, zithunzi mankhwala, mankhwala, mankhwala ndi zina organic kaphatikizidwe.
2.Nthawi zambiri amagwiritsidwa ntchito poyesa ma reagents.Universal solvents ndi non-amadzimadzi titration solvents.Amagwiritsidwa ntchito popanga acetate, cellulose acetate, mankhwala, inki, esters, mapulasitiki, zonunkhira, etc.
3.PH mtengo wowongolera.Angagwiritsidwe ntchito yokonza ethyl acetate, yokonza ulusi, utoto, zomatira, copolymer utomoni, etc., yokonza acetic anhydride, chloroacetic acid, glycolic acid ndi pickling mafakitale.
4.Ikhoza kugwiritsidwa ntchito ku pickling ya mafakitale.Kukonzekera kwa ulusi, zokutira, zomatira, ma copolymer resins, etc.
5.Ndi chinthu chofunika kwambiri cha organic mankhwala opangira mankhwala, omwe amatha kupanga mitundu yosiyanasiyana ya mankhwala.Makampani opanga mankhwala amagwiritsidwa ntchito popanga mankhwala osiyanasiyana, mafakitale opanga utoto amagwiritsidwa ntchito popanga mitundu yosiyanasiyana ya utoto, ndipo makampani opanga mankhwala amagwiritsidwa ntchito popanga zinthu zosiyanasiyana za polima, zomwe ndizofunikira kwambiri pakatikati.Kuphatikiza apo, imagwiritsidwanso ntchito ngati zosungunulira zamafakitale, zowotcha zikopa, zopangira mphira latex coagulants, zida zopangira utoto, zonunkhiritsa zopanga, ma reagents amankhwala, etc., komanso amagwiritsidwa ntchito ngati acidulants, zowonjezera kukoma, etc.
6.Acetic acid angagwiritsidwe ntchito mu pickling ndi kupukuta njira zina, mu ofooka njira acidic monga buffers (monga galvanizing, electroless faifi tambala plating), mu theka-wowala faifi tambala plating electrolyte monga zina, mu nthaka, cadmium passivation njira akhoza kusintha adhesion. filimu ya passivation, yomwe imagwiritsidwa ntchito kawirikawiri kusintha pH ya asidi ofooka plating solution, itha kugwiritsidwanso ntchito ngati zosungunulira zina zowonjezera organic (monga coumarin).
7.Nthawi zambiri amagwiritsidwa ntchito poyesa ma reagents, zosungunulira zambiri ndi zosungunulira zopanda madzi, organic synthesis, synthesis of pigments and pharmaceuticals.
