Dichlorophenol alcohols of formula: or their isomers are prepared by reacting 2,2-bis-(3-chloro-4-hydroxyphenyl)-propane or its isomer with formaldehyde in aqs. alkali at 0-35 degrees C and acidifying the product. The alcohols may be used as cross-linking agents for polymers and as intermediates for polyesters.ISMAIL ROSHDY DIPL-CHEM DRHEUSER GUENTHER DIPL-CHEM DR
Many more mono- and di-nuclear phenol alcohols can form in parallel (Martin, 1956). Some of the phenol alcohols that can form are given in Table 1. Studies on phenol-formaldehyde gel formation at a high temperature and at different pH More results ► Dictionary browser ? ▲ Phenetol phe...
Dairy cows and fresh manure have the potential to emit considerable amounts of alcohols and CH4 and research is needed to determine effective mitigation.doi:10.2134/jeq2007.0357Huawei Suna, Steven L. Trabueb, Kenwood Scogginb, Wendi A. Jacksonc, Yuee Panc, Yongjing Zhaod, Irina L. Malkinac...
consumed according to reaction(77). Alcohol has been found to be absent at the beginning of the reaction and forms only when phenol reacts with epoxides. The epoxides prefer to react with the so-formed alcohols, in the presence of the catalyzing influence of phenols, rather than with phenols...
Phenols do not show the behavior typical of alcohols. In particular they are more acidic because of the electron-withdrawing effect of the aromatic ring. The preparation of phenol itself is by fusing the sodium salt of the sulfonic acid with sodium hydroxide: C6H5SO2.ONa + 2NaOH → C6H5...

Such tandem steps work well with propargylic alcohols (2017S4335) and chloro-iodophenols, without attack at the chloro atom (2005JOC6548) using Pd(OAc)2 and CuI as the catalyst combination; Pd(Ph3P)4–CuI also works well with 1-alkynes (2016CEJ2935). Pd–Cu impregnated on magnetite is ...
