Iindaba zeshishini

Ukucoca ilaphu imathiriyeli ekrwada igubungela ngaphezu kodidi olunye lwemveliso. Ukusuka kwi-solvents zokucoca ezomileyo ezifana neTetrachlorethylene ukuya kwi-nonionic surfactants, i-SLES kunye neentlobo ze-betaine, ukhetho olufanelekileyo luxhomekeke kwinkqubo yesicelo. I-Dotachem ibonelela ngoluhlu lweekhemikhali zokucoca kunye nokhathalelo lwelaphu ezivela e-China, kunye nolwazi lwemveliso, iisampulu kunye namaxwebhu okuthumela ngaphandle akhoyo.

Funda ukuba kutheni i-NP-9 i-Nonylphenol Ethoxylate isetyenziswa ngokuqhelekileyo ekucoceni kwimizi-mveliso, ekusetyenzweni kwamalaphu kunye neenkqubo ze-emulsification, kunye nendlela iDotachem ixhasa ngayo ukhetho lwebakala le-NPE.

Phonononga indlela i-Dimethylformamide (DMF) exhasa ngayo ukudityaniswa kwe-pharmaceutical intermediate synthesis, kutheni i-solvent consistency ibalulekile, kunye nendlela i-Dotachem ibonelela ngayo ngenkxaso yokukhangela evela e-China.

Phakathi kwe-20 kunye ne-Tween 80 zimbini ezisetyenziswa ngokuqhelekileyo ii-Polysorbate surfactants. Eli nqaku lithelekisa ixabiso labo le-HLB, ukusebenza kwe-emulsification kunye nokugxila kwesicelo ukunceda abathengi bakhethe ibakala elifanelekileyo.

Ukukhetha ibakala elifanelekileyo le-Nonylphenol Ethoxylate kufuna ukunyibilika kokulinganisa, ubushushu besicelo, kunye nohlobo lokuqulunqa. Kwiinkqubo zamanzi, i-NP-9 okanye i-NP-10 inokubonelela ngeyona nto ingcono phakathi kwe-solubility kunye ne-emulsification. Kwiinkqubo ezityebileyo zeoli, amabakala aphantsi e-EO afana ne-NP-2 okanye i-NP-4 angenza ngcono ngenxa yamanqaku aphezulu amafu kunye ne-HLB ephantsi.

Eli nqaku lichaza indlela i-EO grade echaphazela ngayo ukusebenza kwe-Cetearyl Alcohol Ethoxylate kwi-emulsions ye-industrial, kwaye yintoni abathengi abafanele baqinisekise ngaphambi kokukhangela kwi-Dotachem.
