标题:About Selective Methods Of Synthesis Of 6-Tert-Butyl-2-Methylphenol And 6-Tert-Butyl-2,4-Dimethylphenol
摘要:Vapor Phase Catalytic Methylation With Methanol Of 2-Tert-Butylphenol At The Temperature 280-300A Degrees C Proceeds Selectively With Formation Of 6-Tert-Butyl-2-Methylphenol. Elevating Reaction Temperature Above 300A Degrees C Leads To Formation Of 2,6-Dimethylphenol. Reaction Of 2-Tert-Butylphenol With Methanol In Alkaline Medium In The Presence Of Zinc Oxide Is Shown To Lead Initially To Formation Of A Mixture Of Calixarenes And Methylenebisphenols That At Elevated Temperature Exert Splitting Leading In Future To 6-Tert-Butyl-2,4-Dimethylphenol. Obtaining It In This Reaction From 2,2'-Methylenebis-(6-Tert-Butyl-4-Methylphenol) Proceeds Selectively. Pathways Of The Reductive Methylation Of Methylenebisphenols With Methanol In Alkaline Medium Is Considered.

标 题 :Improved process for synthesis of hindered amine stabilizers for polymeric materials
发明人：LAI JOHN TA-YUAN
权利人:GOODRICH CO B F
摘要:Process for the synthesis of hindered polysubstituted α-amino acetamides by reaction of a secondary amine with an α-halo acetamide in a basic organic reaction medium and in the presence of a phase transfer catalyst. The product thus obtained can comprise a multifunctional compound having one or more hindered amino moieties. These compounds are highly effective as UV stabilizers in a variety of plastics, especially the alpha monoolefins.

标题:Facile synthesis of symmetric esters of alkylenebisphosphonic acids
发明人：HERLINGER ALBERT W; STEPINSKI DOMINIQUE C
权利人:UNIV LOYOLA CHICAGO
摘要:A facile synthesis of symmetric esters of C 1 -C 10 alkylenebisphopsphonic acids is disclosed in which a C 1 -C 10 alkylenebis(phosphonic dichloride) is reacted with an alcohol in the presence of a catalytic amount of 1H-tetrazole and a base in an aprotic solvent to form a first reaction mixture. The first reaction mixture is maintained for a time period sufficient to form a C 1 -C 10 alkylenebis(chloro ester phosphonate) that is reacted under basic conditions with an excess of a hydroxylated compound to form a second reaction mixture that is itself maintained for a time period sufficient to form a C 1 -C 10 alkylenebis(ester phosphonate) partial ester, homoleptic tetraester or mixed tetraester. The material so formed can be recovered or used as is.
