I-Propionic Acid Lizinga Lavelonkhe (Tincazelo te-GB)
Lizinga lavelonkhe le propionic acid lichaza ngalokucacile kubukeka kwayo: kutawuba ngulokungenambala, lokusabala lokuneliphunga lelibi, futsi umbala wayo kumele uhlangabetane nemazinga lakhetsekile e-colorimetric labonakalako (sib., ngenani le-APHA lelingadluli umkhawulo lobekiwe) kwentela kucinisekisa kutsi lomkhicito uhlangabetana netidzingo telizinga lekubukeka.
Ngekuya kwekuhlanteka, lizinga lavelonkhe ligunyata kutsi kube ne propionic acid lencane lengu 99.0%. Lesidzingo sekuhlanteka lokusezingeni leliphakeme sicinisekisa kutsi i-propionic acid iletsa kusebenta lokucinile nalokwetsembekile kutotonkhe tindzawo letehlukene tekukhicita kanye nekusebentisa timboni. Umswakama locuketfwe yintfo lebalulekile letsintsa lizinga lemkhicito; ngekwelizinga, lokucuketfwe ngemanti kumele kulawulwe ngaphansi kwa 0.5% kwentela kuvikela umswakama lowendlulele kutsi ungaphazamisi tintfo tayo temakhemikhali kanye nekusebenta. Esidi, njengenkhomba lebalulekile, iphindze icaciswe ngalokucacile: le esidi (levetwa njenge mass fraction, lebalwa njenge propionic acid) kumele iwe ngaphansi kwelibanga lelichaziwe kwentela kucinisekisa kusimamisa kwemakhemikhali emkhicito kanye nekuphendvula kuhlangabetana netidzingo. Lokucuketfwe tinsimbi letisindzako kukhawulelwe kakhulu kulelizinga-lead, i-mercury, kanye naletinye tinsimbi letisindzako tikhawulelwe emazingeni laphansi kakhulu, ngalokuvamile tilinganiswa nge ppm (tincenye ngesigidzi), kucinisekisa kuphepha kwekusetjentiswa ekudleni, emitsini, kanye naletinye timboni letibucayi.
Lizinga lavelonkhe liphindze libeke tidzingo leticondzile ngekucina. Ngesikhatsi sekushisa lokubekiwe (sib., 20°C), le density kumele iwe ngaphakatsi kwelibanga lelichaziwe, lokukhombisa kutsi ngabe tintfo letibonakalako temkhicito tiyahambisana nemazinga. Libanga lekubila ngulokunye lokubalulekile lokufanele kucatshangelwe: ipropionic acid kumele ibe nelibanga lekubila lelivame kuba ngu 140°C – 142°C, kucinisekisa kusimamisa kwayo kwekushisa kanye nekungagucugucuki kuhlangabetana netimfuno letihambisanako tetimboni. Lokucuketfwe yi Chloride kulawulwa kakhulu, ngelizinga lelidzinga kutsi emazinga e Chloride abe ngaphansi kwemkhawulo lotsite (sib., 0.001%) kuvikela imitselela lemibi ngelizinga lemkhicito kanye nekucubungula lokulandzelako. Lokucuketfwe yinsimbi kuphindze kube ngaphansi kwemikhawulo lecacile, levame kungabi ngetulu kwa 0.0001%, kugwema tintfo tensimbi letitsintsa umbala, kusimamisa, kanye nekusebenta kwe propionic acid etincenyeni letitsite letikhetsekile.
Mayelana nekuncibilika, lizinga lavelonkhe lidzinga ipropionic acid kutsi ikhombise kuncibilika lokuhle etinhlayiya letitsite (sib., ethanol, diethyl ether), kuvumela kuhlanganiswa lokuphelele ngetilinganiso letitsite kwentela kuhlangabetana netidzingo tekwakheka kutotonkhe timo letehlukene tekusebentisa.

Shandong Pulisi Chemical Co., Ltd. ngumkhiciti lokhetsekile kanye nemphakeli we-propionic acid lesezingeni lelisetulu yetimboni eChina, letinikele ekuletseni kuhlanteka lokungagucuki, kuniketa lokutsembekile, kanye netisombululo letilungiselelwe emakhasimende etimboni emhlabeni wonkhe. I-propionic acid yetfu ikhicitwa ngaphansi kwemazinga lacinile e-GB/T 10615, ngekuhlanteka kwelizinga le-premium kufinyelela ≥99.5% kanye nelizinga lekucala ku-≥99.0%, lefaka umswakama lophansi, lokucuketfwe kwensimbi lephansi, kanye nemazinga ensimbi lasindzako lalawulwako kuhlangabetana netidzingo letifunako te-e-use ehlukahlukene.
Yakhiwe ngebuchwepheshe be-propylene oxidation lobutfutfukile, i-propionic acid yetfu icinisekisa timphahla temakhemikhali letizinzile, kuncibilika lokuhle kakhulu, kanye nelizinga lelihambisanako le-batch ngemuva kwe-batch. Isebenta njengentfo lebalulekile lesemkhatsini ekuhlanganisweni kwetilwane, kukhicita emapulasitiki, tindlela te electroplating, kudla kanye nekugcinwa kwekudla, kanye nekukhicita imitsi kanye ne agrochemical. Isekelwe lelabhorethri yetfu yekulawula lizinga lelingaphakathi kanye netindlela tekuhlola letiphelele, yonkhe imitfwalo ihambisana ne-COA lephelele, i-MSDS, kanye naletinye tincwadzi tekuhambisana kwenta kube lula kungeniswa lokubushelelezi kanye nekusetjentiswa emhlabeni wonkhe.
Ngeminyaka lengetulu kwekutfumela emave e-Asia, eYurophu, eMphumalanga Lesekhatsi, nangale, siniketa tindlela tekupakisha letigucugucukako, intsengo lencintisanako, kanye nemigomo yekuletsa letsembekile lefaka ekhatsi i-FOB, i-CIF, ne-DDP. Noma ngabe udzinga ema-oda lamancane ekulinga noma tintfo letiningi letiningi, licembu letfu lelitinikele likulungele kuniketa kusekelwa kwetebucwepheshe lokuphendvulako kanye nenkonzo leyentiwe ngekwemvelo kuhlangabetana netidzingo takho tebhizinisi letihlukile.
