The difference was 0.07 in favor of 98E5 on average, meaning that using 95E10 gasoline, which has a higher ethanol content, increases consumption by 0.7%. When the measurements are normalized, the difference becomes 1.0%, a result that is highly consistent with an estimation of calorific values based on approximate fuel composition, which came ...
Phase behavior Triple point: 150 K (−123 °C), 0.00043 Pa Critical point: 514 K (241 °C), 63 bar Std enthalpy change of fusion, Δ fus H o +4.9 kJ/mol
The increased solubility of water with higher ethanol content permits E30 and hydrated ethanol to be put in the same tank since any combination of them always results in a single phase. Somewhat less water is tolerated at lower temperatures. For E10 it is about 0.5% v/v at 21 °C and decreases to about 0.23% v/v at −34 °C. [30]

According to RFA the ethanol industry created almost 154,000 U.S. jobs in 2005, boosting household income by $5.7 billion. It also contributed about $3.5 billion in federal, state and local tax revenues. [45] The return on investment (ROI) to upgrade a service station to sell E15 is quick given today's markets.

In 2009 Brazil produced 27.5 billion liters (7.26 billion U.S. liquid gallons), [13] representing 35.9% of the world's total ethanol used as fuel. Sugar cane plantations covered 3.6 million hectares of land for ethanol production, representing just 1% of Brazil's arable land, with a productivity of 7,500 liters of ethanol per hectare, as ...
For homopolymerization of ECC 1.5 to 3 wt. % of an initiator are added. Above 3 wt% initiator no further acceleration was found, increasing proportions of initiators, however, increase the brittleness of the formed thermoset. After a photopolymerization usually still a thermal post-curing is necessary for a complete reaction. [5]
