The BIMCO Liquid Cargo database is intended for use by for shore-side staff and to some extent for newcomers to the tanker trade and should only be used as a reference tool providing brief information regarding the more than 360 of the commonly transported liquid cargoes including Diphenyl. Trade name/synonym name: Biphenyl; Biphenyl Crude; Diphenyl Crude; Phenylbenzene; PHPH; Bibenzene; Lemonene; Xene. Main Properties: Diphenyl appears as a clear colourless liquid with a pleasant odour. Diphenyl occurs naturally in coal tar, crude oil, and natural gas. Toxic. High melting point. Very toxic to aquatic life. Main chemical and physical properties: Flash point: Approx. 110°C Boiling Points: Around 255°C Viscosity: @ 20°C Unknown Vapour pressure: @ 20°C < 5 kPa Density: depending on composition - around 995 kg/m3 at carriage temperature IBC carriage requirements: IBC chapter 17 Ship Type 2 Tank Type 2G Relevant additional IBC requirements: 15.19.6 high-level alarm 16.2.6 the cargo's viscosity at 20°C shall be specified on a shipping document. If the cargo's viscosity exceeds 50 mPa.s at 20°C, the temperature at which the cargo has a viscosity of 50 mPa.s shall be specified in the shipping document 16.2.9 cargo's melting point shall be specified in the shipping document MARPOL Annex II Pollution Category X Special information to be added to Shipping Document: The cargo's viscosity at 20°C shall be specified on a shipping document. If the cargo's viscosity exceeds 50 mPa.s at 20°C, the temperature at which the cargo has a viscosity of 50 mPa.s shall be specified in the shipping document The cargo's melting point shall be indicated in the shipping document Stowage: Heat adjacent: Yes Stow adjacent to fuel oil tanks: Yes Carriage requirements: Heating during voyage: Carriage temperature depends on composition. Can be from 65 - 75°C Therefore, carefully follow heating instructions Heating during unloading: Unloading temperature depends on composition. Can be from 70 - 80°C,
