CYCLIC POLYSULPHIDES FROM PARKIA SPECIOSA

Five polysulphides have been isolated from Parkia speciosa.The structures of four of these have been established as 1,2,4-trithiolane, 1,2,4,6-tetrathiepane, 1,2,3,5,6-pentathiepane (lenthionine) and 1,2,4,5,7,8-hexathionane.A further product has been tentatively assigned either the 1,2,4,6,7- or 1,2,4,5,7-pentathiocane structure.Key Word Index - Parkia speciosa; Mimosaceae; cyclic polysulphides; lenthionine.

COMPOSITION FOR OPTICAL MATERIAL AND OPTICAL MATERIAL USING THE SAME

The present invention provides a composition for an optical material containing a ring compound (a) represented by formula (1), an episulfide compound (b), and sulfur (c), wherein the content of the ring compound (a) in the composition for an optical material is in the range of 5-70 mass %, the content of the episulfide compound (b) is in the range of 20-90 mass %, and the content of the sulfur (c) is in the range of 1-39 mass %. (In the formula, X represents S, Se or Te. a to f=0 to 3, 8≥(a+c+e)≥1, 8≥(b+d+f)≥2, and (b+d+f)≥(a+c+e).) This composition for an optical material has a high refractive index as an optical characteristic, and has sufficient heat resistance and good mold release characteristics.
