Process which comprises ozonizing a solution of a product having the formula: ##SPC7## at temperatures below ambient room temperature with not more than equimolecular equivalent of ozone in the form of oxygenfree ozone or an oxgyen-containing ozone mixture, and decomposing the ozonization product in the presence of a reducing agent suitable for reducing ozonization products to aldehydes, selected from the group consisting of an iodide, a sulphite, a bisulphite, formaldehyde, sulphur dioxide, pyridine, hydrazine hydrate, a sulphide, hydroquinone, zinc or magnesium in acidic solution. Raney-nickel, phosphorus (III)-compounds, tri-lower alkyl-phosphites and hydrogen, to form the product having the formula: ##SPC8##
