- Sodium borohydride redn. of stone groundwood pulp from spruce (Picea abies) had no dramatic effect on the light-induced brightness reversion. This indicates that the direct scission of phenacyl aryl ether linkages is not an important step in the initial chromophore formation.

Tidskriftsartikel (refereegranskat)abstract
- A series of 4-omega-carboxyalkoxyphenyl-4'-methoxybenzoates 2 underbar has been prepared. Compounds with a spacer length of n=3 and n=5 show liquid crystalline behaviour. The products were characterized by IR and H-1NMR -spectroscopy, mass spectrometry, optical microscopy and DSC -measurements. The compounds are potentially useful as side-groups in liquid-crystalline polymers.
