Beschreibung

Anwendung

Semiconductor grade methanol may be used to degas indium antimonide wafers. Poly(amidoamine) (PAMAM) was coupled with carboxylic acid terminated Si surfaces by soaking the Si surfaces in methanol. Methanol may be used to degrease silicon ingots and ribbons. It may be used in the purification of surfactant (sodium diethylhexylsulfosuccinate) and to prepare a colloidal suspension of silicon.
