Novel gem-bis (hydroxymethyl) alcohols of formula I
[wherein m, n, p, q, r, s and t are integers the sum of which is z which has a value of from 12 to 20; n, q and s, which is y, having a value of from 1 to 3; m, p and r, which may be the same or different each has a value of from 0 to 16; and t has a value of from 3 to 19] and mixtures thereof with diols of formula IIA
[wherein h' and k' are integers; k' is greater than or equal to 3; h' is greater than or equal to 1; and the sum of h' and k' is from 12 to 20).
There is also provided a series of processes for preparing these gem alcohols and mixtures from formyl alcohols and a process for preparing these formyl alcohols from unsaturated alcohols. The compounds and mixtures of the invention are particularly useful in the preparation of polyurethanes.
