Trends in Chemical Consulting estructuring in the chemical industry has created a wealth of opportunities . . " * * · · . i>. l l f for consultants. Companies are now more willing to seek outside help than in the past as they recognize the value of experienced specialists. But what constitutes the efficient use of a consultant? And is consulting for you? Trends in Chemical Consulting explores these issues through contributions from chemical consultants, those who have used the services of a consultant, and partici &0ΨΙ pants in cooperative arrangements. Presen m tations focus on those considerations specific to consulting relationships between scientific professionals. Chemists, chemical engineers, and other scientific professionals in support areas to the chemical industry will find this an indispensible resource of infor mation on chemical consulting.
