Karoly Borbely, who serves as state secretary with the Economy Ministry, will replace Constantin Dascalu in the position, Oltchim said.
Dascalu resigned early February, citing personal reasons. He had been appointed chairman of the board in September 2011.
Dascalu replaced general manager Constantin Roibu, after the Economy Ministry decided the two positions couldn’t be held by the same person.
The Economy Ministry owns 54.8% in Oltchim.
Tuesday, Oltchim closed down 0.85% at RON1.289 a share in Bucharest.
