Additional information

2 -methylbut-2 -ene has a Henry's Law Constant of 11145 Pa.m3/mol. The value has been taken from a regulatory review document, the OECD SIDS document (OECD 2004). This is supported by data calculated based on the physico-chemical properties of the substance and the equation set out in the Guidance R16 (ECHA 2012) and data from the QSAR estimation (US EPA 2009).
