A green and eco-friendly method for preparation of oleochemicals from Camelina oil was developed
for possible application for bio-lubricant basestocks, The steps involved are consisting of epoxidation
of Camelina oil based fatty acid followed by further branching with wide range of alcohol such as
2-propanol, n-butanol, isoamyl alcohol and 2-ethylhexanol. These products were evaluated with
physico-chemical properties such as acid value, oxirane oxygen content (OOC), hydroxyl value, low
temperature properties, viscosity at 40 and 100 °C, viscosity index and characterized by FTIR, 1H
NMR. The appearance of peak at 824 cm–1 in the FTIR spectra was due to the formation of epoxy
group and broad peak appeared at 3500-3300 cm–1 is for hydrogen bonded O-H stretching vibration of
hydroxy group. The 1H NMR spectra showed a signal at 2.9-3.2 ppm region indicated CH-proton
attached to the oxygen atom of the both epoxy group for epoxidized product, peaks for newly formed
secondary alcohols emerged at 4.25-3.35 in alkoxy derivatives. The Camelina based synthetic product
may find application in biolubricants base stock.
Background
Entisol is a very poor, compact, and low-water-holding capacity soil. They are obstacles to the plant's root system's penetration and the availability of water, particularly in dry months. However, Arbuscular mycorrhizae fungi (AMF) is used for seedling growth and reduces water stress in the plant.
Results
In this experiment, the growth parameters and the physiological activities of the plant were changed for the well watering (WW), fractionated watering (FW), and stopped/no watering conditions of the T. arjunaseedling. This experiment demonstrated higher mycorrhizal dependency (24.90%) under the FW condition than that of the WW condition (18.58%). Also the root colonization was higher (67%) under FW plants compared to WW plants (53%) associated with AMF+ in T. arjuna seedling. Photosynthesis was found 24.27% more with FW than the WW condition. Experiment' shows posivitivecorrelation between the photosynthesis and interval of no watering for AMF− plants (r2 = 0.873 for AMF− (control) and comparatively very weak for plants with AMF+ (r2 = 0.259 for AMF+ plants).
Conclusions
The findings confirms the use of AMF in entisol soil to improve plant growth and biomass by reducing edaphic stress.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
