Abstract: 2-(substd)-3,4-dihydro-2-H-pyran cpds, of formula (I) (where R1-4 are each H or hydrocarbyl and R5 is hydrocarbyl, in which the gps opt. have an inactive substit. and two of the gps may be combined to form a ring structure), are prepd. by reacting an, beta-unsatd. carbonyl cpd. R2-C=CHR3, e.g. acrolein, with a vinyl ether: e.g. methyl vinyl ether, in the presence of a zinc halide, or an aluminium halide or nitrate. In an example acrolein (purity 98%) methyl vinyl ether and zinc chloride were placed in an autoclave, and the resultant mixture was heated up to 90 degrees C in 15 mins with stirring, kept at 90 degrees C for 30 mins and cooled. The resulting colourless transparent liquid was analyzed by gas chromatography, to indicate no unreacted acrolein present. The reaction product was washed with water and distilled to give at first unreacted methyl vinyl ether and then 2-methoxy-3,4-dihydro-2H-pyran as a distillate boiling at 127 degrees C. The yield from acrolein was 95%.

Title: Turtle shell degreased and impregnated with synthetic resin - e.g. acrylic! glass used to make ornamental goods
IPC: B44C5/00
Filed: 1978-02-08
Abstract: Cleaned and degreased turtle shell is coated with or enveloped in a transparent or translucent synthetic resin, pref. by impregnating practically entirely with the resin. The resin is pref. one of the following thermoplastic materials: acrylic glass, polycarbonate, styrene-acrylonitrile copolymer, or acrylic ester-styrene-acrylonitrile, hard polystyrene, styrene-butadiene copolymer, or an epoxide resin. Cleaning is pref. carried out in an acid bath pref. contg acrylic or formic acid, and degreasing with a solvent, pref. 1,1,1-trichloroethane or trichloroethylene. The shell is dried before application of the resin, which is then polymerised and hardened. The prod. can be heat-formed. The prods. are used to make e.g. artistic goods, table-ware, ornaments, etc. of various types. The supply of natural turtle shell is limited, and there are difficulties in working with it. Coating with synthetic resin helps to overcome these problems, the resin forming a bond with the shell and thus enabling the composite to be worked as a whole. The resin also helps to bring out the natural design of the shells.
