Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Substance decomposes during vapour pressure testing (OECD104). Because of rapid hydrolysis, vapour pressure of isopropyl alcohol released from the substance is used in CSA. 

Key value for chemical safety assessment

Vapour pressure:
60.2 hPa
at the temperature of:
25 °C

Additional information

The vapour pressure of the substance was determined by using isothermal thermogravimetric effusion method according to OECD 104 and in accordance with GLP. Vapour pressure cannot be determined because the test substance decomposes during testing. Based on the peer-reviewed handbook, the vapour pressure of the substance is 1.33 hPa @ 63.2 deg. C (Thomas & Davies 1969). No value is available at room temperature.

Titanium tetraisopropanolate is hydrolytically unstable. When it comes in contact with water or moisture, a complete hydrolysis will take place with no significant reaction products other than isopropyl alcohol (IPA) and hydrated titanium dioxide. Because of rapid hydrolysis, read-across data on the vapour pressure of IPA (CAS no 67-63-0) released from the substance is used as a key value in CSA (peer-reviewed handbook value, Lide 2000).
