Surface sulphide formation on high-temperature corrosion resistant alloys in a H2S-HCl-CO2 mixed atmosphere

In this paper the corrosion behavior of high temperature corrosion resistant alloys is investigated in a gas atmosphere containing HCl and H2S at 480 degrees C and 680 degrees C. By considering the vapor pressures of the metal chlorides and the water gas shift reaction, as well as the influence of H2S, the different corrosion behavior at 480 degrees C compared to 680 degrees C can be explained and a model of the course of corrosion is proposed. Corrosion tests were performed for 240 h with the austenitic stainless steels S31400 (20 wt% Ni) and N08811 (30.4 wt% Ni) and with the Ni-based alloy N06600 (72.5 wt% Ni). It could be shown that with increasing Ni-content in the alloy, the corrosion rate at high temperatures decreased, but this effect could no longer be observed at lower temperatures. While for N08811 and N06600 the mass loss was lower at 680 degrees C, it increased at temperatures of 480 degrees C. In the case of S31400 the mass loss increased with rising temperature.

The synthetic route is as follows.

Representative experimental procedure for carboxylative coupling reaction Taking the carboxylative coupling of 4-methylphenylacetylene, cinnamyl chloride (2a), and CO2 as example: A 70 mL oven dried autoclave containing a stir bar was charged with AgI (0.5 mg, 0.002 mmol) and Cs2CO3 (978 mg, 3.0 mmol). 4-Methylphenylacetylene (232 mg, 2.0 mmol), cinnamyl chloride (458 mg, 3.0 mmol), and 20 mL dry DMF were added with syringe, respectively, after purging the autoclave with CO2 three times. The sealed autoclave was pressurized to appropriate pressure with CO2. The reaction mixture was stirred at 60 C for 24 h, then the autoclave was cooled to room temperature and the remaining CO2 was vented slowly. The reaction mixture was diluted with water (30 mL) and extracted with ethyl acetate (3*30 mL). The combined organic layers were washed with water and brine, dried over Na2SO4, and filtered. The solvent was removed under vacuum. The product (E)-cinnamyl 4-methylphenylpropiolate (3b) (502 mg, 1.82 mmol, 91% yield) was isolated by column chromatography on silica gel (ethyl acetate/petroleum ether: 1:25).
