Fa'atomuaga puupuu ile p-tert-butylphenol

P-tert-butyl phenol tioata paepae, mu, ma sina manogi phenol.Liu liusuavai 98-101 ℃, vevela 236-238 ℃, 114 ℃ (1.33kPa), va'aiga fa'atatau 0.908 (80/4 ℃), fa'asino igoa 1.4787.Solu i le acetone, benzene, methanol, soluble teisi i le vai.E mafai ona fa'asao i le ausa vai.

Sauniuniga o le p-tert-butylphenol 1. E saunia mai le phenol ma le isobutene faʻatasi ai ma le cation exchange resin e fai ma faʻamalosi.2. Saunia e ala ile tali ole phenol ma le diisobutene.I le faaopoopo atu i le tert-butylphenol, o le p-octylphenol e gaosia foi i le gaioiga o le tali.3. O le oloa maeʻa na maua e ala i le faʻaalia o le phenol ma le tert-butanol pe a uma ona fufulu, faʻamalama, vavaeeseina o le centrifugal ma faʻamago.

Fa'aogaina o le p-tert-butyl phenol 1. Fa'aaogaina i le suau'u soluble phenolic resin, ma formaldehyde condensation e mafai ona maua ai le tele o talosaga o oloa.I totonu o le chloroprene adhesive fefiloi 10-15% o le oloa, ina ia maua soluble resin, o lenei ituaiga o pipii e masani ona faʻaaogaina i felauaiga, fausiaina, tagata lautele, faia o seevae, ma isi. lomitusi, ata maualuluga ma isi.I totonu o le insulation varnish, e mafai ona faʻaaogaina i le coil dip varnish ma laminate varnish.2. Faʻaaogaina mo le gaosiga o le polycarbonate, e pei o le phosgene polycarbonate faʻamutaina sui sooupu, faʻaopoopo le aofaʻi o le 1-3% o resini.3. Faʻaaogaina mo epoxy resin, xylene resin suiga;E pei o le polyvinyl chloride stabilizer, surfactant, UV absorber.4. O lo'o i ai mea fa'aantioxidant ma e mafai ona fa'aogaina e fai ma fa'amautu mo pa'u, fasimoli, chlorinated hydrocarbons ma nitrocelluloses.O se mea mataʻutia foʻi o le faʻafefe o iniseti (vailaau), acaricide acaride (pesticide) ma le mea e puipuia ai laau, manogi, resini gaosia, ma e mafai foi ona faʻaaogaina e fai ma faʻamalulu, solvent, vali ma faʻapipiʻi vali.E mafai foi ona faʻaaogaina e fai ma mea e faʻaaogaina ai le demulsifier mo le suauʻu fanua ma faʻaopoopoga mo le suauu taʻavale.
