CommentsonPhysico-ChemicalProperties

Measurementsofpourpoint,specificgravity,watersolubilityandflashpointwereperformedbyAnalyticalSciencesattheChevronResearchTechnologyCompany,Richmond,California.Afulltestreportwassubmittedforwatersolubilityonly.

Accordingtothenotifier,noboilingpointcouldbedeterminedforCP7077.Atabout215oC,componentsbegintodistillaway.Atabout420oC thefinalcomponentsbegintodecompose.Thenotifierhasalsoindicatedthat thevapourpressure isnegligibleduetothenotifiedchemical’sionicnature.

Concentrationsofthenotifiedsubstanceinwaterweredeterminedbythetotalorganiccarbon(TOC)analysisoftheequilibratedsolutionsbasedonpercentcarboninformation.

Thenotifiedchemicaldoesnotcontainanyhydrolysablefunctionalgroupsthoughstrongacidwillneutralisethecalciumsalt.Hence,thereactionsofthesubstancewillbeverylimitedanditwillbestableinwaterwithrespecttotheenvironmentalpHrange5–9.

Thenotifierhasestimatedthepartitioncoefficienttobe3.Thoughtherearenotestreportsto support thisclaim,the estimatedvalue seemsappropriatedue the highmolecularweightandhighhydrocarboncontentofthesubstance.Thisvalueisrelativelyhighandthechemicalcan be expected to bindstronglyto, orbe associatedwith, soil and sediment. Hence, due tothedetergentnatureofOLOA271(strongsurfaceactivity)andmicelleformationtendencies,theOLOA271willtendtopartitionfromwatertosolidsororganicmatter.

Thenotifiedchemicalwillnotdissociate.Althoughthechemicalcontainscalciumsalts,the
