|Appearance( 25ºC)||white flakes|
|PH Value (1% aqueous solution)||7±1.5|
|Free Amine Content(%)||≤0.50|
|Boiling point||235.0±0.0 °C at 760 mmHg|
|Stability||Flammable liquid, good moisture absorption. It is a mixture of cis and trans isomers. It has the properties of ordinary olefin and|
primary alcohol. In the presence of acids, heating to form 2, 5-dihydrofuran or butenal, especially cis isomers, is easy to react.
Heating to above 165℃ gradually dehydration occurs polymerization reaction
|Flashing point||85.4±16.4 °C|
|Storage condition||Store sealed. The products are packed in brown glass bottles protected in wooden cases.|
