HCl is frequently used to increase production. Add inhibitor chemicals to reduce acid stimulation and metal corrosion. Oil and gas well corrosion is successfully inhibited by amphiphilic amino pyridine derivatives. In this study, three cationic amphiphilic amino pyridine derivative inhibitors were synthesized and evaluated by FT-IR and 1H NMR analysis. These inhibitors exhibit cost-effective, eco-friendly, and highly effective inhibition reactivity for corrosion prevention. The surface activity was evaluated at 25⁰,40⁰ and 60 °C in 1 mol HCl, where CMC values increase and surface tension decreases as temperature increases. The corrosion inhibition efficacy (%η_w) was determined using gravimetric methods at various temperatures of 25⁰,55⁰, and 70 °C which revealed that SAHBR has a higher efficacy (94.5% at 25 °C, 92.3% at 55 °C and 91.1% at 70 °C) than SADBR (92.9% at 25 °C, 90.5% at 55 °C and 88.4% at 70 °C) and SAOBR (91.6% at 25 °C, 89.7% at 55 °C and 87.0% at 70 °C) for 400 ppm dose. Also, the inhibition efficacy (%η_p) which determined through potentiodynamic polarization technique which display SAHBR is 95.90% higher than SADBR is 93.90% and SAOBR is 89.90% at 25 °C for 400 ppm dose and electrochemical impedance spectroscopy (EIS) practice which parade the inhibition efficacy (%η_E) of the synthesized inhibitors where SAHBR is 91.7% higher than SADBR is 89.0% and SAOBR is 87.3% at 25 °C for 400 ppm dose.

This paper presents a novel trial for filling commercial vinylester (VE) resin with glass fiber (GF), as one filler component, in dual directions to prepare water pipe composite using the continuous winding technique, for the first time. 10% to 25% VE-GF composites were prepared with distributing GF in axial and hoop directions. The composites were cured via in-situ polymerization; the crosslinked network is occurred between catalyst and unsaturation sites in prepolymer. All concentrations show stability in all stages of thermal degradation, compared with blank VE; the more stable composite is 25% VE-GF. GF filled in axial and hoop directions enhanced the mechanical strength of both axes. The improved concentration (20% VE-GF composite) increased axial tensile strength and hoop tensile strength respectively to 32 MPa and 51 MPa, compared with 22 MPa and 42 MPa for blank VE. Furthermore, this concentration enhanced the strengths of surface harness and pull off from 39 BHC and 2.2 MPa to 46 BHC and 5.3 MPa, respectively. The 25% VE-GF composite decreased these values, but still higher than blank. GF improved the resistance of vinylester toward water absorption in different immersion conditions, especially the 25% VE-GF composites. The filling direction doesn’t affect the composite stability.

The preparation methodology of CEM membranes was performed in two steps; functionalization followed by fabrication. Firstly, cellulose powder was functionalized with trichloroacetic acid at different reaction times to prepare carboxymethyl tricellulose (CMTC). In the second step, the exchange memberane was fabricated via phase inversion technique using the functionalized cellulosic material and polyethylene glycol as a pore former. The prepared CEM was fully characterized using FTIR, SEM, mechanical properties, and degree of substitution (DS) determination. The morphological microstructure of the CEM membrane was investigated and discussed. The microstructural analysis by FTIR confirmed the functionalization process. The tensile values obtained at different reaction times showed the effectiveness of using trichloroacetic acid in the carboxymethylation and consequently, the stability of the obtained functionalized cellulose. The obtained DS values are higher than that of the commercial CMC and also the published values. It has been observed that the prepared CEM have an average DS value of 1.5 and therefore much higher than the DS value of commercial CMC whose DS ranges between 0.7 and 1.2.
