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
complexnatureofthissubstanceandthetendencytoformmicellesindicatesdissociationisunlikely.

Overall,270kgofwasteOLOA271isreleased/annum/customersitesinAustralia.AssumingthatAPIoilseparationresultsin95%removaloftheoilfromwastewater(asclaimedbythenotifier),thenapproximately13.5kgofOLOA271perannumislikelytoenterthesewersfromeachoftheblendingsites.

During use, OLOA 271isnot substantially alteredanddoesnotdecomposein thecrankcase
duetoits highthermalstability.However, thismaterial isburnedin theengine oilduringoilconsumption.TheinsolublesandparticulatematterbecomecoatedwithOLOA271detergentandcan be filteredout of theoil.
