Abstract: A method for increasing moisture retention in a soil includes applying an effective amount of an effective humectant composition to the soil. The effective humectant composition is identified by determining the average moisture content of the soil for the humectant compositions applied at a minimum humectant concentration level, a maximum humectant concentration level, and at a first concentration level between the minimum and the maximum humectant concentration level. An average slope curve is generated by plotting the determined average moisture content of the soil for each applied humectant concentration levels from the minimum humectant concentration level to the maximum humectant concentration level. An effective humectant composition is determined when the generated average slope curve provides an increasing average moisture content along the entirety of a length of the generated average slope curve and when the generated average slope curve has a p value of 0.05 or less.

Abstract translation: 增加土壤中水分保持的方法包括将有效量的有效保湿剂组合物施用于土壤。 通过确定在最小保湿剂浓度水平，最大保湿剂浓度水平和在最小和最大保湿剂浓度水平之间的第一浓度水平下施用的湿润剂组合物的土壤的平均含水量来确定有效湿润剂组合物。 通过绘制从最小保湿剂浓度水平到最大保湿剂浓度水平的每个施加的保湿剂浓度水平的测定的土壤的平均含水量，产生平均斜率曲线。 当产生的平均斜率曲线沿着所产生的平均斜率曲线的整个长度提供增加的平均含水量并且当产生的平均斜率曲线具有0.05或更小的p值时，确定有效的保湿剂组成。

Abstract: A polyol includes the reaction product of an epoxidized oil and an organic acid. The epoxidized oil and the organic acid are reacted in the presence of a Lewis base catalyst including at least one of a phosphorous atom or a nitrogen atom. The polyol is formed by a method that includes the step of reacting the epoxidized oil with the organic acid in the presence of the Lewis base catalyst.

Abstract: A proppant includes a particle present in an amount of from 90 to 99.5 percent by weight and a polymeric coating disposed about the particle and present in an amount of from 0.5 to 10 percent by weight, based on the total weight of the proppant. The polymeric coating is formed from a curable composition comprising an isocyanate, an acrylate, and a polyol. A method of forming the proppant includes the steps of combining the isocyanate, the acrylate, and the polyol to form the curable composition, coating the particle with the curable composition, and curing the curable composition to form the polymeric coating.

Abstract: A process for increasing the wetting rate of hydrophobic media with a wetting composition includes the steps of combining water and a heteric polyol to form the wetting composition, aging the wetting composition for an amount of time sufficient to increase the cloud point of the wetting composition to greater than 23 °C, and applying the wetting composition to the hydrophobic media. The heteric polyol has the following formula: X[Y(CH2CH2O)a(CH2CHCH3O)bH]c wherein X is an organic core derived from an initiator having at least two hydroxyl groups; Y is a heteric copolymer comprising at least two different alkyleneoxy units selected from the group of ethyleneoxy units, propyleneoxy units, and butyleneoxy units; the subscripts a and b are independently zero or a positive integer and at least one of a or b must be a positive integer; and the subscript c is an integer of two or greater.
