Phthalic Anhydride, Sauni mo La'uina~

Talosaga:

Muamua, o le phthalic anhydride e iai sona sao taua i le gaosiga o vailaʻau. Ose mea autu autu mo le gaosiga o vailaʻau faʻamaʻi, vailaʻau gastrointestinal, vailaʻau faʻamaʻi, vailaʻau faʻamaʻi ma isi vailaʻau. E le gata i lea, o le phthalic anhydride foi o se mea muamua mo le sauniaina o hormones eseese o laau e pei o le hormone tuputupu aʻe ma auxin, lea e taua tele mo le faʻaleleia o le tuputupu aʻe o laau ma faʻateleina fua o fua.

Lona lua, o le phthalic anhydride o loʻo faʻaaogaina lautele i le vali ma mea manogi. I le avea ai o se vaeluaga mo vali ma mea manogi, o le phthalic anhydride e faʻaaogaina e fai ai mea manogi, pigments, synthetic fiber dyes, ma isi mea.

E le gata i lea, o le phthalic anhydride e iai foi sona sao taua i le gaosiga o palasitika ma paʻu. O se mea taua tele mo le gaosiga o polymer compounds e pei ole polyphenylene ether, polyamide, ma le polyimide. O nei polymer compounds o loʻo i ai mea faʻapitoa faʻapitoa ma mautu kemisi, ma e faʻaaogaina lautele i taavale, eletise, fausiaina ma isi fanua, e maua ai le lagolago malosi mo le atinaʻeina o sosaiete faʻaonaponei.

I le tulaga o le faʻaogaina o meaola, o le phthalic anhydride o loʻo i ai le tele o faʻaoga. E mafai ona faʻaaogaina mo carbonylation, propylene oxidation, sauniuniga o esters carbon faʻagaoioia, hydrogenation mago, aldehyde ma ketone esterification, nitric acid ma alkaline oxidation. I le faʻaogaina o mea faʻapitoa, e mafai ona faʻaogaina le phthalic anhydride e faʻapipiʻi ai masima ammonium, ma e mafai foi ona faʻaaogaina e avea ma sui autu polymerization mo le faʻaogaina o le kopa zinc sulfide. O nei gaioiga fa'akomepiuta e maua ai se fa'avae mauoa mo le atina'eina o alamanuia kemikolo.

E le gata i lea, o le phthalic anhydride e iai foʻi mea taua i le tulaga o vailaʻau lelei. E mafai ona faʻaaogaina mo le eseese o le vavaeeseina o le crystallization ma catalytic reactions, ma e mafai foi ona faʻaaogaina mo le sauniuniga ma le faʻasalalauina o tekonolosi o le tele o polymers calcium sulfur inorganic. I le gaosiga o le mining, e mafai ona faʻaaogaina le phthalic anhydride mo le faʻaogaina o minerale o faʻaputuga e faʻaleleia ai le lelei o le mining ma le lelei o le oa. E le gata i lea, o le phthalic anhydride e mafai foi ona faʻaaogaina e avea o se mea mataʻutia mo iniseti ma vailaau faʻasaina, o loʻo faia se sao taua i le faʻamautinoaina o le tuputupu aʻe o fualaʻau ma faʻateleina fua.

I le gaosiga o alamanuia, phthalic anhydride e masani ona faʻaaogaina e avea o se solvent ma extractant. Ona o le maualalo o le vevela ma le maualuga o le solubility, o le phthalic anhydride o loʻo faʻaaogaina lautele i le suauʻu faʻamamaina ma pisinisi petrochemical e pei o se mea mataʻutia. I le taimi lava e tasi, e mafai foi ona faʻaaogaina e avea o se suʻesuʻega chromatographic suʻesuʻega ma se mea faʻapipiʻi mo mea manogi, ma isi, e tuʻuina atu ai se auala aoga mo suʻesuʻega vailaʻau ma mea faʻalaʻau.

E le gata i lea, e mafai foi ona faʻaaogaina le phthalic anhydride e saunia ai le vanillin, fuafua le suka urine, saunia le tele o synergists ma antifreeze, ma isi. O se tasi foi lea o mea mataʻutia mo le faia o polyvinyl chloride stabilizers ma se filifiliga lelei mo togafitiga luga o uʻamea. I le pa'u ma le palasitika gaosiga, phthalic anhydride e mafai ona fa'aogaina e fai ma mea fa'apipi'i pa'u ma mea fa'apipi'i palasitika e fa'aleleia ai le fa'atinoga o oloa ma le lelei.
