Cent., Pittsburgh, PA 15236, USA). Prepr. Pap. - Am. Chem. Soc., Div. Fuel Chem., 30(2), 35-40 (English) 1985. CODEN: ACFPAI. ISSN: 0569-3772. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) With regard to org. S removal from coal, o-thiocresol [137-06-4] was the major product and PhMe [108-88-3] was the minor product in treatment of benzothiophene [95-15-8] with 1:1 KOH-NaOH at 375° for 30 min, but the product ratio was reversed when the reaction time was 3 h. The treatment was the most effective at (wt. ratio) NaOH-KOH. Dibenzothiophene [132-65-0] was unreactive at 375° and reaction time 30 min, but it quant. reacted at 400° and reaction time 3 h to yield ~50 wt.% CH2Cl2-sols., 35 wt.% o-phenylphenol [90-43-7], and 10 wt.% biphenyl [92-52-4].

Benzenethiols as inhibitors for the corrosion of copper

Benzenethiols as inhibitors for the corrosion of copper. Sankarapapavinasam, S.; Ahmed, M. F. (Dep. Chem., Bangalore Univ., Bangalore 560 001, India). J. Appl. Electrochem., 22(4), 390-5 (English) 1992. CODEN: JAELBJ. ISSN: 0021-891X. DOCUMENT TYPE: Journal CA Section: 72 (Electrochemistry) Section cross-reference(s): 56, 66 The effect of benzenethiol (BT) and some substituted benzenethiols {o-Me benzenethiol (o-MBT), o-amino benzenethiol (o-ABT), p-amino benzenethiol (p-ABT) and m-Me benzenethiol (m-MBT)} on the corrosion of Cu in H2SO4 and NaOH solns. has been investigated by means of spectrophotometric measurements, potentiostatic polarization studies, cyclic voltammetry and potential stepping expts. In acid solns., under ordinary conditions, the thiols are adsorbed onto the metal surface in their mol. forms through their thiol (-SH) moiety, and when the potential is made more noble oxidative dimerization of the thiols takes place, and the dimer replaces the thiol. Both thiols and their dimers are not effective as inhibitors. In alk. solns. in-situ polymn. of thiol takes place to yield polythiol which is a very effective inhibitor both in acidic and alk. 7440-50-8 and 137-06-4 are just another two chemicals used in this study. media. .
