METHOD FOR MANUFACTURING α-METHYLSTYRENATED PHENOL

According to an embodiment of the present invention, the present invention provides a method for manufacturing α-methyl styrenated phenol, which comprises the following steps: (a) making phenol react with α-methyl styrene (AMS) under the presence of a first acidic catalyst to obtain a first product; and (b) additionally making 1-5 equivalents of α-methyl styrene for 1 equivalent of phenol react with the first product under the presence of a second acidic catalyst to obtain a second product. The manufactured α-methyl styrenated phenol does not generate environmental damage and is economical.(a) Making phenol react with α-methyl styrene (AMS) under the presence of a first acidic catalyst(AA) Obtaining 30-50 wt% of TMPI, 1-10 wt% DMP, 5-20 wt% of cumyl phenol, 1-10 wt% of AMS trimer, and the remaining phenol(b) Additionally making the α-methyl styrene react with a first product under the presence of a second acidic catalyst(BB) Obtaining 5-50 wt% of TMPI + DMP, 2-20 wt% of cumyl phenol, 1-10 wt% of dicumene, 20-60 wt% of dicumyl phenol, and 0.1-5 wt% of AMS trimerCOPYRIGHT KIPO 2017

Surface reactivity of non-hydrolytic silicophosphate xerogels: A simple method to create Br?nsted or Lewis acid sites on porous supports

Non-hydrolytic sol-gel reactions of silicon acetates with trimethylsilyl (TMS) esters of phosphoric and phosphonic acids produce cross-linked matrices containing homogeneous dispersions of silicate and phosphoryl groups connected together by networks of Si-O-P(=O) linkages. The condensation degrees reach 80 to 90%. Residual organic groups (10 to 20%) were reacted with a variety of compounds (H2O, Me3SiOSiMe3, POCl3, SiCl4, AlMe3, Al(NMe2)3, and AlCl3) in order to enrich the surface of these porous matrices with Br?nsted (≡P-OH) and Lewis (tetracoordinated Al) acid functional groups. The differences in the reactivity of ≡Si-OAc and ≡P-OSiMe3 groups were utilized for the selective modification at the silicon and phosphorus atoms. The reaction procedures were optimized and significantly porous silicophosphate materials with a high content of either hydroxyl groups or four-coordinated aluminium species were obtained. The activity and selectivity of prepared samples as catalysts for the dimerization of α-methylstyrene were tested. Excellent activities and moderate to very high selectivities were achieved suggesting the potential use of silicophosphate xerogels in heterogeneous catalysis.

Highly efficient catalytic dimerization of styrenes via cationic Palladium(II) complexes

A highly efficient head-to-tail dimerization of a styrene was developed using a cationic palladium(II)-catalyzed selective C-C bond forming reaction. The complex [AllylPd(PPh3)]+OTf-, which is believed to generate 'palladium hydride' (Pd-H), catalyzed the dimerization of various styrenes in excellent yields as single isomers. This Pd(II)-catalyzed reaction provides a new economical C-C bond forming method. Copyright
