Endlelo ra Acetylene ya Propionic Acid
1.Ku Lunghiselela Switirhisiwa swa Raw swa Propionic Acid
Switirhisiwa leswi nga tirhisiwangiki eka endlelo ra acetylene swi katsa acetylene, oxygen na mati. Acetylene yikumeka kusuka eka ti refineries kumbe ti khemikhali, kasi oxygen yikumeka kusuka eka ti air separation units.
2. Endlelo ro Angula
Pretreatment: Acetylene na oxygen swi pretreated hiku hambana kuya eka mahiselo lawa ya faneleke ku tiyisisa leswaku reaction yi famba kahle.
Carbonylation Reaction: Acetylene na oxygen leswinga tshunguriwa khale swi hlanganisiwa kutani swi endliwa carbonylation reaction eka vukona bya catalyst. Goza leri rihumelela ehansi ka swiyimo swa mahiselo yale henhla na ntshikelelo, hi ntolovelo eka 180–200°C na 0.8–1.2 MPa.

Propionic Acid – Khamphani ya Tikhemikhali ya Shandong Pulisi, Ltd.         info@pulisichem.cn
Shandong Pulisi Chemical Co., Ltd. i muphakeri wo tshembheka na muendli wa propionic acid (CAS 79-09-4) eChina, a tisa switirhisiwa swa xiyimo xa le henhla leswi nga na tikhetane ta mphakelo leti tiyeke na tisisiteme to tika ta vulawuri bya khwalithi. Propionic acid ya hina, leyi tivekaka tani hi propanoic acid, i short-chain saturated fatty acid leyingana molecular formula ya CH3CH2COOH na ntiko wa molecular wa 74.08. Yivonaka tani hi mati lawa yangariki na muhlovo, yo basa, naswona ya bola lawa yanga na nun’hwelo wo biha wa xihlawulekisi, naswona ya hlangana hiku hetiseka na mati, ethanol, ether, na swin’wana leswi tolovelekeke swa organic solvents.
Hi humelerisa propionic acid hiku tirhisa maendlelo ya xiyimo xale henhla ya indasitiri ya synthesis, ku tiyisisa ku basa kale henhla xikan’we na matirhelo lawa yanga cincekiki eka switirhisiwa swohambana hambana swa ti indasitiri. Tanihi xitirhisiwa xa nkoka xa ti khemikhali ta organic, propionic acid ya hina yitirhisiwa ngopfu eka swiyenge swotala: eka indasitiri ya swakudya na swakudya, yitirha tani hi xihlayisi lexi hlayisekeke na lexi tirhaka kahle na xisivela mold eka mavele, swilo leswi bakiweke, na swakudya swa swifuwo, loko yitlhela yi tirha tani hi xitirhisiwa xoka xinga tirhisiwanga ku humelerisa sodium propionate na calcium propionate; eka bindzu ra tikhemikhali, yi tirha tani hi esterification agent, solvent ya nitrocellulose, plasticizer, na intermediate ya nkoka eka ku endla swidlaya switsotswana, fungicides na swihlanganisi swa nun’hwelo; ku engetela kwalano, yikuma switirhisiwa eka ti electroplating solutions, vumaki bya mirhi, na tani hi viscosity inhibitor eka vuhumelerisi bya biya.
Eka Shandong Pulisi Chemical, hi rhangisa khwalithi ya swikumiwa na ku eneriseka ka vaxavi. Propionic acid ya hina yi pakiwa eka swigubu swa ntolovelo kumbe mathangi ya ISO ku fikelela swilaveko swo hambana swa logistics na vuhlayiselo, na swiletelo swa vuhlayiseki bya xiphurofexinali leswi nyikiweke eka ku khoma, ku fambisa, na ku hlayisa. Hi nyika vukorhokeri bya oda ya vunyingi na lebyi endleriweke wena, hi khathalela swilaveko swo karhi swa tikhayente ta misava hinkwayo ku suka eka swifundzha swo hambana. Hi malembe ya vutshila eka vuhumelerisi bya tikhemikhali na mabindzu ya le handle, hi tiyimiserile ku nyika swikumiwa swa xiyimo xa le henhla swa asidi ya propionic, minxavo yo phikizana, na nseketelo lowu tirhaka kahle endzhaku ka ku xavisiwa ku aka vuxaka bya ntirhisano bya nkarhi wo leha na vatirhisani emisaveni hinkwayo.
