tetraethylene glycol (polyethylene glycol, polymers, ... Materials (hierarchy name)) |
|
Note: A polyethylene glycol in the form of an odourless and non volatile hygroscopic liquid characterised by two hydroxyl groups and three ether linkages. It is a mixture comprising some high and low molecular weight glycols, but consisting mainly of tetraglycol. It has been used in conservation to stabilize waterlogged archaeological wooden objects.

Additional Notes: |
|
| Dutch ..... Een polyethyleenglycol in de vorm van een geurloze en niet-vluchtige hygroscopische vloeistof, die twee hydroxylgroepen en drie etherverbindingen heeft. Het is een mengsel van glycolen van hoog en laag moleculair gewicht, maar bestaat voornamelijk uit tetraglycol. Bij conservering wordt het gebruikt om met water doortrokken houten archeologische vondsten te stabiliseren. |
