Fa'amatalaga
Dibutyl phthalate, e lauiloa foi o le dibutyl phthalate poʻo le dibutyl phthalate, Igilisi: Dibutylphthalate, o se sua suauʻu manino e leai se lanu ma se kalave faʻapitoa o le 1.045 (21°C) ma le vevela o le 340°C, e le mafai ona solu i le vai, vai-soluble ma feʻaveaʻi O mea totino e matua maualalo lava, e pei o le enolthalate e matua maualalo lava, ae o mea totino e matua maualalo lava, e pei o le enolthale. eter, acetone ma benzene, ma e mafai foi ona fefiloi ma le tele o hydrocarbons. Dibutyl phthalate (DBP), dioctyl phthalate (DOP) ma le diisobutyl phthalate (DIBP) o mea faʻapipiʻi masani e tolu, o mea faʻapipiʻi, paʻu gaosia ma paʻu paʻu, ma isi mea e masani ona faʻaaogaina. E maua i le esterification vevela o le phthalic anhydride ma le n-butanol.
Meatotino tau vailaau
Sua suau'u manino le lanu ma sina manogi manogi. Solu i totonu o solu masani masani ma hydrocarbons.
Fa'aaogāga
- Faʻaaogaina e fai ma mea faʻapipiʻi mo nitrocellulose, cellulose acetate, polyvinyl chloride, ma isi. O lenei oloa o se plasticizer. O lo'o i ai le malosi fa'afefeteina i resini eseese.
- Faʻaaogaina mo le gaosiga o le PVC, e mafai ona tuʻuina atu le malu lelei i oloa. Ona o lona taugofie ma lelei le faagasologa, e matua faʻaaogaina, toetoe lava tutusa ma le DOP. Ae ui i lea, o le volatility ma le suʻeina o vai e fai si tele, o le mea lea e le lelei le umi o le oloa, ma o lona faʻaaogaina e tatau ona faʻasolosolo faʻatapulaʻa. O lenei oloa o se palasitika sili ona lelei o le nitrocellulose ma e malosi le malosi o le gelling.
- Faʻaaogaina mo nitrocellulose coatings, ei ai se aafiaga faʻamalulu lelei. Tulaga sili ona mautu, faʻafefeteina, faʻapipiʻi ma le vai. E le gata i lea, o le oloa e mafai ona faʻaaogaina e fai ma plasticizer mo polyvinyl acetate, alkyd resin, ethyl cellulose ma neoprene, ma e mafai foi ona faʻaaogaina i le gaosiga o vali, faʻapipiʻi, paʻu paʻu, vaitusi lomitusi, tioata saogalemu, celluloid, vali, vailaʻau faʻamaʻi, solvents manogi, lubricants ie, ma isi.
- I le avea ai o se palasitika mo cellulose ester, masima ma paʻu masani, polystyrene; e faia ai le polyvinyl chloride ma ona copolymers malulu-tetee mo le tuufaatasia o meaola, ion selective electrode additives, solvents, insecticides, plasticizers , Gas chromatography stationary vai (maualuga le faaaogaina o le vevela 100 ℃, solvent o le acetone, benzene, dichloromethane, ethanol), o le taofiofia ma le tuueseeseina o mea manogi, o mea manogi ma le vavae ese. mea e maua ai le okesene (alcohols, aldehydes, ketones, esters, etc.).
