“…From the analysis of fatty acid composition (Table 6), linseed oils from the two varieties were characterized by a very stable proportion of polyunsaturated fatty acids with a high content of alpha-linolenic acid (more than 57%) that is the most important fatty acid in linseed. For the high content of this fatty acid, linseed oil is highly reactive and oxidatively unstable and, consequently, mainly used in paints, resins, varnishes, printing inks, linoleum, and more recently, in polymer and oleochemical products, such as epoxidised linseed oils for plastic formulation (Hill, 2000;Salimon et al, 2012;Samarth and Mahanwar, 2015). It is also being investigated for use in the building and construction industry (Desroches et al, 2012).…”

Agronomical evaluation and chemical characterization of Linum usitatissimum L. as oilseed crop for bio-based products in two environments of Central and Northern Italy

In the recent years, new perspectives for linseed (Linum usitatissimum L.) are open as renewable raw material for bio-based products (Bb), due to its oil composition, and the interesting amounts of coproducts (lignocellulosic biomass). Therefore, the possibility to introduce linseed crop in two environments of central and northern Italy, traditionally devoted to cereal cultivation, has been evaluated. Twoyears field trials were carried out in the coastal plain of Pisa (Tuscany region) and in the Po valley (Bologna, Emilia Romagna region), comparing two linseed varieties (Sideral and Buenos Aires). Agronomical evaluation (yield and yield components), seed and oil characterization (oil, protein content, and fatty acid composition), together with carbon (C) and nitrogen (N) content of the residual lignocellulosic biomass were investigated. The two varieties, grown as autumn crop, showed a different percentage of plant survival at the end of winter, with Sideral most resistant to cold. The achieved results showed significant influence of cultivar, location and growing season on yield and yield components, as well as on chemical biomass composition. In particular, Sideral appeared to be the most suitable variety for tested environments, since higher seed yield (3.05 t ha -1 as mean value over years and locations) and above-ground biomass (6.98 t ha -1 as mean value over years and locations) were recorded in comparison with those detected for Buenos Aires (1.93 and 4.48 t ha -1 of seed production and lignocellulosic biomass, respectively). Interestingly, in the northern area, during the 1 st year, Buenos Aires was the most productive, despite its low plant survival at the end of winter, which determined a strong reduction in plant density and size. In such conditions, the plants produced a larger number of capsules and, consequently, high seed yield (3.18 t ha -1 ). Relevant differences were also observed between the two years, due to the variability of climatic characteristics (temperature levels, and moisture regimes). All these findings confirmed as, in linseed, yield and yield components are quantitatively inherited and influenced by both genotype and environment (location and climate). Varietal and environmental effects were also recorded for oil content and yield, and, generally, good oil percentages, for both genotypes, were found (ranging from 44 to 49% on dry matter basis). Oil from the two varieties was characterized by a stable proportion of polyunsaturated fatty acids with a high content of alpha-linolenic acid (more than 57%), that makes this oil suitable to be used in paints, resins, varnishes, linoleum, polymers and oleochemicals. Finally, our results pointed out as above-and below-ground biomasses, were different in terms of quantity, and chemical characteristics (N, C and C/N ratio). Interesting amounts of N and C could return into the soil by crop residues (stem portions and roots), thus underling the possibility to maintain and/or increase the soil organic matter pool.

“…They are used in several areas such as food, pharmaceutical, cosmetic, personal care, textile, paint, coatings, and life sciences. [1][2][3][4] The demand for both better as well as biocompatible surfactants leads to the growing need of new surfactants with improved performances, better surface active properties, and least toxicity. [5] Dimeric or gemini surfactants are made up of two head groups and two hydrocarbon tails per molecule linked by either a rigid or a flexible spacer.…”

The present work reports the synthesis and evaluation of surface active properties of amino acid-based gemini surfactants, namely, sodium dilauraminocystine (SDLC) and sodium dimyristaminocystine (SDMC) derived from L-cystine and fatty acids. The effect of reaction variables like molar ratio of raw materials and temperature has been studied for the synthesis of these gemini surfactants. In preparation of these gemini surfactants, fatty acids (lauric/myristic) were reacted with thionyl chloride to obtain respective acid chlorides (lauroyl/myristoyl). These acid chlorides were further reacted with L-cystine at different reaction conditions to get amino acid based-gemini surfactants. The study revealed that 1:2.5 molar ratio of reactants, namely, L-cystine and lauroyl/ myristoyl chloride and 10-15 reaction temperature resulted in maximum yield of amino acid-based gemini surfactants (SDLC and SDMC). Surface active properties of synthesized gemini surfactants (SDLC and SDMC) were also compared with their corresponding monomeric units, namely, sodium lauroyl cysteine (SLC) and sodium myristoyl cysteine (SMC), respectively. The results demonstrated that gemini surfactants (SDLC and SDMC) had better surface active properties than their corresponding monomeric units. The structures of synthesized amino acid-based gemini surfactants were also confirmed by FTIR, 1 H NMR, 13 C NMR, and ESI-MS spectral data.

“…A possible explanation for our results is that the extra oxygen moieties on these compounds help the compounds adhere to the metal surface and reduce friction especially under load. These molecules undergo chemical transformation at the metal contact zone and develop a stable tribochemical fi lm for further protection 30,31 .…”
