Abstract
A survey of 27 galactic star-forming regions in the 6(K) - 5(K) and 5(K) - 4(K) CH3CN lines at 110 and 92 GHz, respectively, was made. Twenty-five sou rces were detected at 110 GHz and nineteen at 92 GHz. The strongest CH3CN e mission arise in hot cores in the regions of massive star formation. CH3CN abundance in these objects is increased up to 10(-9) or larger Weaker CH3CN lines were found in a number of sources. They may arise in warm (30-50 K) clouds.
