摘要：NOVELTY - The invention relates to a process for synthesizing three-dimensional cubic phase MCM-48 which comprises, charging hexadecyl trimethyl-ammonium bromide into the alkaline water solution of n-ethyl orthosilicate, mixing homogeneously and charging small amount of oxygen negative ion accelerating agent, agitating acutely for 1h, transferring into polytetrafluoroethylene cup for water thermal crystallization at a finite temperature, subjecting the obtained product of crystallization to sieving, scouring to neutral, drying to obtain the raw powder, sintering the obtained raw powder at 550 deg. C for6h.
