摘要： The prodn. of polyalkyl-1-oxa-diazaspirodecane cpds. of formula (I) comprises reacting a cpd. of formula (VI) with an epihalohydrin of formula (V) in the mole ratio of (1:1)-(1:10), in organic solvent and in the presence of alkali hydroxide (AOH) as the soln. catalyst and then (for n > 1) heating the resulting epoxide (VI) at 100-240 degrees C. The AOH consists of 1-20 moles solid alkali metal hydroxide or a mixt. thereof with water in the wt. ratio of (1:9)-(9:1) and the solvent comprises alcohol(s) and opt. an inert organic solvent. n = 1-50; Y = a gp. of formula (II) or (III) (indices 3 and 4 indicate ring positions in I, with the N atom attached to a CH2 gp. in the propylene-2-oxy gp.); R = H, O, NO gp., 1-12 C alkyl or alkoxy, allyl, 1-22 C acyl, benzyl or 3-12 C cycloalkoxy; R = R = H or 1-5 C alkyl and R = Me; or R = H or 1-5 C alkyl and R + R + attached C atoms = 5-6 C cycloalkyl gp. or a gp. of formula; R , R = H, 1-30 C alkyl or 7-12 C phenylalkyl (opt. substd. with Cl or 1-4 C alkyl); or R + R + attached C atom = 5-18 C cycloalkyl (opt. substd. with up to four 1-4 C alkyl gps.) or a gp. of formula; if n = 1, R is absent, i.e. the O and the terminal CH2 gp. form an oxirane ring; if n > 1, R = H or 1-22 C acyl; or R may be absent in the terminal monomer unit with an oxirane ring present as above; HX = acid residue or a salt thereof with a protic acid; Hal = Cl, Br or I.

摘要： The invention relates to a process for the preparation of polyalkyl-1-oxa-diazaspirodecane compounds, which can be used as highly active light stabilizers for polymers. The action is carried out in a solvent mixture of at least one alcohol and if appropriate an inert organic solvent in the presence of solid alkali metal hydroxide or a corresponding amount of a mixture of solid alkali metal hydroxide and water as the sole catalyst. The process offers the advantage that, by using a solvent mixture and dispensing with a phase transfer catalyst, a higher rate of reaction and therefore higher product quality with the same yield are achieved. By dispensing with a phase transfer catalyst, which remains in the waste water and must be disposed of expensively, and by the reusability of the solvent mixture, the process is more environmentfriendly and more economical than processes known to date.
