Reaction of ferrocenylphenylcarbinol with ethereal solution of boron trifluoride in dichloride methane formed the relevant ferrocenylphenylmethyl carbocation.
The bulk and solution photopolymerization of vinyl butyl ether were studied using diph-enyl-4-thiophenoxyphenyl sulfonium salt (DPTS) as photoinitiator.
To continue the natural identified chemical after that,we have found that 4-(4-hydroxyphenyl)-2-butanol(Rhododendrol:RD)inhibited the melanin synthesis more than Arbutin did.
This paper initially discussed synthesis and modification of tetrafunctional epoxy resin(1,1,2,2- tetrakis(hydroxy phenye)ethane),as well as application in copper clad laminate.
As the isocyan group is polymerized further, diphenyl carbondiimine may be formed, further polymerization of which forms a nitrogen-containing polycyclic aromatic compound.
N butyl 2 ethoxy thioacridone was prepared from o chloro benzoic acid and p phenetidine by means of Ullman reaction,cyclization,N alkylation and sulfurization.
Ethyl phenylacrylate intermediate bringing a double bond was introduced first,which is subsequently transformed into triketone and then DCM was obtained with high purity.
The main synthetic methods of o-phenylphenol were reviewed.The method and research status of dehydrogenation to o-phenylphenol after cyclohexane condensation reaction were discussed detailedly.
A new tetrakis( p glycylglycinephenyl)porphin and its rare earth (Yb,Sm) complexes were synthesized.They have been characterized by elemental analysis,UV vis,IR, 1HNMR and laser Raman spectra.
As shown by study the extracting powers of two extraction agents are changed with acidy of developer extracting power N,N-diphenyl glycine is stronger than N-n-butyl glycine for 5 metal ions.
The synthetic medium of optical N acylalanines was N (2,6 xylyl) alanine.It was reacted with 1 menthol and prepared into its menthol esters which were purified by TLC, resolved and determined by HPLC.
Named Kevlar, this alternating blend of 1,4-phenylene-diamine and terephthaloyl chloride combine at the molecular level to form a series of parallel chains.
