“… 43 The stretching of the aromatic C–C group is associated with the peak at 1460.12 cm –1 . 44 Compared with the FTIR spectrum of the heated poly-NDTHDC, all of the above-listed peaks are intact, confirming the TGA results that poly-NDTHDC is stable in 15 wt % HCl solution and also thermally stable. The broadness of the peaks at around 3380 and 2680 cm –1 may be due to the entrapped water molecules.…”

N 1 , N 1 -diallyl- N 6 , N 6 , N 6 -tripropylhexane-1,6-diaminium chloride (NDTHDC) and its polymer poly( N 1 , N 1 -diallyl- N 6 , N 6 , N 6 -tripropylhexane-1,6-diaminium chloride) (poly-NDTHDC) were synthesized and tested against API X60 carbon steel corrosion in 15 wt % HCl solution. Weight loss, electrochemical, and surface analysis techniques were used. Results show that poly-NDTHDC is better than NDTHDC. Moreover, 1000 mg/L NDTHDC protected the studied surface by 79.1% at 25 °C, while 100 mg/L poly-NDTHDC afforded 86.1% protection. Inhibition efficiency increases with temperature (up to 60 °C) but depreciates thereafter. NDTHDC and poly-NDTHDC perform better under the hydrodynamic condition than the static condition. TGA and FTIR results reveal that poly-NDTHDC is chemically and thermally stable.

“…Due to the poor mechanical properties of CP-based biomaterials, combining CPs with biopolymers is gaining increasing interest. Chitosan (CH) based CPs have found applications in bone tissue engineering, where chitosan enabled room temperature processing of composite materials with corrosion protection of implant [5,6]; CH and heparin coatings showed increased deposition rate and improved blood compatibility [7]. Cataphoretically synthetized CH/HAp coatings on Ti substrate in two-step process are obtained [8], some chitosan multilayered coatings were used as multifunctional implants [9] and amorphous calcium phosphate (ACP) was shown to be good candidate for protein protection [10].…”

“…The calculated values of K ads for the GBS and SBS are 3936.6 and 4610.7, respectively. At present, the issue of calculating the thermodynamic parameters of adsorption is extremely tangled. − We believe that the only way to determine the type of adsorption is to study the temperature dependence of the corrosion process. It provides the value of adsorption enthalpy, which characterizes the adsorption type (physisorption or chemisorption).…”

Dual-Function Synergists Based on Glucose and Sucrose for Gas Hydrate and Corrosion Inhibition

et al. 2020

The increasing demand in the modern world for energy resources leads to the recovery of oil and gas fields in remote northern and Arctic regions. The development of additives that effectively prevent complications such as gas hydrate formation and corrosion is a relevant issue. In this work, a method for the modification of simple carbohydrates was proposed, which allows one to obtain reagents that are effective both in hydrate inhibition (in the form of synergistic additives to commercial hydrate inhibitors) and prevention of corrosion. Modification of glucose and sucrose was carried out by incorporation of two sulfonate and carboxyl groups into their structures. Synergists were used as bisodium salts. PVCap-based inhibitors (Luvicap EG and Luvicap 55W) were utilized as commercial kinetic hydrate inhibitors. This study has revealed that mixtures of the proposed reagents with PVCap-based polymers showed a significant synergistic effect. The temperature of hydrate onset decreased by 3.5 °C with the addition of 0.1 wt % of synergist to 0.5 wt % of PVCap-based KHI. Moreover, these reagents also effectively inhibited the corrosion of pipeline steel in 2 M HCl solution. Thus, the proposed synergists will reduce the harmful effects on the environment, risks of accidents, and operating costs due to their biocompatibility and gas hydrate and corrosion inhibition.
