Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption potential of Cyclobutanate was determined in a study according to OECD TG 121(HPLC). Under the conditions of the test, the determined log Koc value was 3.14 (equivalent Koc = 1510 L/kg). Based on this value the substance indicates that it will have moderate potential to adsorb to sediment/soil.
The Henry's Law Coefficient was estimated by EUSES, based on the measured vapour pressure (11.2 Pa at 25°C) and water solubility 11.5 mg/l at 20°C). For Cyclobutanate this results in: Henry coefficient at 25°C is 10.9 and 12°C it is 5.22 Pa-m3/mol.
Based on Level III distribution modelling using EPISUITE (assuming equal and continuous releases to air, water and soil) using SMILES formula CCCC(=O)OC3CC1CC3C2CC=CC12 (The Cas no of Cyclobutanate presents a mistake in the chemical structure) and the measured physico-chemical parameters, water solubility and log Kow as input, it is estimated that the majority of the substance released to the environment will partition mainly into soil (80%) and water (18.5%) with small amounts to sediment and air (both <1%).
The SimpleTreat model, which is incorporated in EUSES, simulates the distribution of the substance in a Sewage Treatment Plant. The results of this show that the substance will not be degraded and that 77.2% of the substance will partition to water, 15.4% to sewage sludge and 7.35% to air.
Additional 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.
