Vsevolod I. Blinoff, 74, an internationally known chemist and chairman of the board of Alcolac, Inc., a specialty chemical company, died suddenly of a heart ailment while playing golf Friday at Kenwood Country Club.

Dr. Blinoff held more than 100 patents in the chemical field, and head both the Baltimore-based Alcolac company and Wapora, Inc., an environmental research and consulting firm that he founded in 1968. In a month Alcolac is scheduled to open in Sedalia, Mo., a chemical manufacturing plant designed to cut down sharply on pollutants that have plagued that industry.

Born in St. Petersburg, Russia, Dr. Blinoff received a Ph.D. in chemistry from the University of Dorfat in Estonia. He taught chemistry at the Arts et Metiers school in Paris, and in 1947 came to the United States. He founded Alcolac soon after.

Dr. Blinoff also was named honorary French consul for the city of Baltimore, an appointment he received from the French government in early 1974 in gratitude for his service to France during the Nazi occupation in World War II. An enthusiastic golfer and hunter, he lived in Washington, and attended the Russian Orthodox Church of St. Nicholas.

Dr. Blinoff is survived by his wife, Marie-Louise, of the home; two sons; Peter, of Fort Lauderdale, Fla., and Ivan, of the home, and three daughters, Martha, or Portland, Maine, Nina, of Denver, and Sandra, of the home.
