Description of key information
The following were submitted to assess the boiling point of dibutyltin di(acetate):
BNT Chemicals (2010) Boiling point of Dibutyltindiacetate. Testing Laboratory: BNT Chemicals GmbH, Parsevalstraβe 29, 06749 Bitterfeld. Report No: BNT 5144-2. Report date: 2010-06-25
The study was performed in house to a recognised guideline EU Method A.2, using the dynamic method. The study was therefore considered adequate for assessment and assigned a reliability score of 2.
The following was included as a supporting study to the key study for the data requirement, boiling point:
Acros Organics (2007) Material Safety Data Sheet dibutylin diacetate pract. Bibliographic source: website https://fscimage.fishersci.com/msds/75959.htm. Owner company: Acros Organics N.V., One Reagent Lane, Fair Lawn, NJ 07410. Company study No.: ACC #75959. Report date: 2007-03-16
The boiling point of dibutyltin di(acetate) was determined to be 114, 130 and 146°C at pressures of 0.27, 0.67 and 1.33 kPa respectively.
Key value for chemical safety assessment
Additional information
A reliability rating of 2 was assigned to the key study, BNT Chemicals (2010), according to the criteria of Klimisch, 1997 as the study was conducted in-house to recognised guidelines, however only summary reports were provided with minimal information on methods and results. The boiling point of dibutyltin di(acetate) was determined to be 114, 130 and 146°C at pressures of 0.27, 0.67 and 1.33 kPa respectively.
Supporting information is also available from an Acros Safety data sheet (2007). The result was reported as 139 ºC at 5 mm Hg.
A reliability rating of 4 was assigned as the safety data sheet is secondary source of information.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
