Imo yemolekyuli:C8H4O3
Inombolo yeCAS:85-44-9
Ulwakhiwo lwemolekyuli yemveliso:
I-anhydride ye-Phthalic yi-organic compound kunye ne-formula ye-C6H4 (CO) 2O.Yi-anhydride ye-phthalic acid.Esi siqina esingenambala siyikhemikhali ebalulekileyo kwimizi-mveliso, ngakumbi kwimveliso enkulu yeeplastiki zeplastiki
.I-anhydride ye-Phthalic yikhemikhali ebalulekileyo ephakathi kwishishini leeplastiki apho kuthatyathwe kuyo ii-phthalate esters ezininzi ezisebenza njengeplastiki kwiintlaka zokwenziwa.I-Phthalic anhydride ngokwayo isetyenziswa njenge-monomer kwii-synthetic resins ezifana ne-glyptal, i-alkyd resins, kunye ne-polyester resins.
I-Phthalic anhydride ikwasetyenziswa njenge-precursor ye-anthraquinone, i-phthalein, i-rhodamine, i-phthalocyanine, i-fluorescein, kunye nedayi ye-xanthene.
I-Phthalic anhydride isetyenziselwa ukuhlanganiswa kwee-amine eziphambili, i-fungicide yezolimo i-phaltan, kunye ne-thalidomide.Ezinye iimpendulo nge-phthalic anhydride zivelisa i-phenolphthalein, i-benzoic acid, i-phthalylsulfathiazole (i-agent ye-intestinal antimicrobial), kunye ne-orthophthalic acid.
Ikhompawundi yikhemikhali ephezulu yeetoni kwaye isetyenziswa ngokubanzi kwiindidi zemveliso ye-organic syntheses.
I-Phthalic anhydride isetyenziswa ekwenzeni iipolyester ezingaxutywanga kunye ne-ejenti yokunyanga i-epoxy resins.Xa isetyenziswe njenge-pigment, inokuba noxanduva lokwazisa kubasebenzi be-ceramic.
I-Phthalic Anhydride yi-organic compound kunye ne-anhydride ye-phthalic acid (P384480).I-Phthalic Anhydride yikhemikhali ebalulekileyo kwimizi-mveliso edla ngokusetyenziswa kwimveliso emikhulu yeeplasticizers f okanye iiplastiki.Uphando lwakutsha nje luye lwavavanya i-Phthalic Anhydride njenge-arhente yokulwa ne-antibacterial.
ukwenziwa kwe-phthaleins, i-phthalates, i-benzoic acid, i-indigo yokwenziwa, i-resins eyenziweyo (glyptal).
EliPhakathi kwiiPlastizer, iipeyinti, iiDayi kunye neePigments, iiResins zePolyester.
I-Chemwin inokubonelela ngoluhlu olubanzi lwee-hydrocarbons ezininzi kunye nezinyibilikisi zeekhemikhali kubathengi bamashishini.Ngaphambi koko, nceda ufunde olu lwazi lulandelayo olusisiseko malunga nokwenza ishishini nathi:
1. Ukhuseleko
Ukhuseleko yeyona nto iphambili kuthi.Ukongeza ekunikeni abathengi ngolwazi malunga nokusetyenziswa ngokukhuselekileyo nokuhambelana nokusingqongileyo kweemveliso zethu, sikwazimisele ekuqinisekiseni ukuba imingcipheko yokhuseleko lwabasebenzi kunye neekontraka ziyathotywa ukuya kutsho kubuncinane obufanelekileyo nobunokwenzeka.Ngoko ke, sifuna ukuba umthengi aqinisekise ukuba imigangatho efanelekileyo yokukhutshwa kunye nokugcinwa kwemigangatho yokhuseleko idibene ngaphambi kokunikezelwa kwethu (nceda ubhekisele kwisihlomelo se-HSSE kwimimiselo jikelele kunye neemeko zokuthengisa ngezantsi).Iingcali zethu zeHSSE zinokubonelela ngesikhokelo kule migangatho.
2. Indlela yokuhambisa
Abathengi banokuodola kwaye bahambise iimveliso kwi-chemwin, okanye banokufumana iimveliso kwisityalo sethu sokuvelisa.Iindlela ezikhoyo zothutho ziquka iilori, uloliwe okanye uthutho lweendlela ezininzi (kuyasebenza iimeko ezahlukileyo).
Kwimeko yeemfuno zabathengi, sinokucacisa iimfuno zeenqanawa okanye iitanki kwaye sisebenzise imigangatho ekhethekileyo yokhuseleko / ukuhlaziya kunye neemfuno.
3. Ubuncinci bobungakanani bomyalelo
Ukuba uthenga iimveliso kwiwebhusayithi yethu, ubungakanani obuncinci bomyalelo ziitoni ezingama-30.
4.Intlawulo
Indlela yokuhlawula eqhelekileyo itsalwa ngokuthe ngqo kwiintsuku ezingama-30 kwi-invoyisi.
5. Amaxwebhu okuhanjiswa
La maxwebhu alandelayo anikwe ngokuziswa ngakunye:
· Ibhili yokuLading, i-CMR Waybill okanye olunye uxwebhu olufanelekileyo lwezothutho
· Isatifikethi sokuHlalutya okanye ukuThobela (ukuba siyafuneka)
· Amaxwebhu anxulumene neHSSE ngokuhambelana nemigaqo
· Amaxwebhu ezinto eziqhelekileyo ngokuhambelana nemigaqo (ukuba kuyafuneka)
