Glycerin, known as glycerol or glycerine, is the principal co-product of biodiesel production, produced through a NaOHor KOH-catalyzed transesterification of the triacylglycerols in oils or fats with an alcohol. Glycerin is known to be a valuable ingredient for producing food, soaps, cosmetics and pharmaceuticals. Currently, with plenty of glycerin available to the world market, more uses are e...

Anaerobic digestion of manure is a widely accepted technology for energy production. However, only a minimal portion of the manure production in the EU is anaerobically digested and occurs predominantly in codigestion plants. There is substantial potential for biogas plants that primarily operate on manure (>90%); however, the methane yields of manure are less compared to coproducts, which is o...

Two studies were conducted with refined glycerin (97.7 and 97.5% glycerin for studies I and II, respectively) to determine ME content and effects on growth performance and carcass and pork quality measures of finishing pigs. An energy balance study using 24 barrows (21.5 ± 0.6 kg initial BW) determined the apparent ME content of glycerin using a generalized randomized block design with 2 dietar...

CLINICALCHEMISTRY, Vol.32, No. 7, 1986 1411 using samples of a quality-control product (Monitrol, Dade). Lanolin, mineral oil, petrolatum, and the hand lotion withoutglycerin did not affect the results. Glycerin and all hand lotions containing glycerin falsely increased them by 60 to 3900 mgfL. We have been informed that KOdak plans to supply sample tips in a packaging that precludes their hand...

Glycerin is a potential feedstock for hydrogen production because one mole of glycerin can produce up to four moles of hydrogen. In addition to glycerin, several potential biorenewable feedstocks, such as triglycerides and their derivatives, could be used for hydrogen production. The major challenge in using such feedstocks in a hydrogen-producing reformer is atomizing these viscous feedstocks ...

Glycerin has been employed for a number of years for the conservation of vaccine virus t and other materials of similar nature, e. g., the virus of rabies, clavele, rinderpest, and foot and mouth disease. Its preservative properties for animal and vegetable tissues are also well recognized. It has, however, been employed more as a diluent, particularly in the case of bovine virus, than because ...

OBJECTIVE To compare the efficacy of glycerin suppository versus no suppository in preterm very-low-birthweight neonates for improving feeding tolerance. DESIGN Randomized controlled trial. SETTING Level III neonatal unit from Mumbai, India. PARTICIPANTS 50 very-low-birthweight (birth weight between 1000 to 1500 grams)preterm (gestational age between 28 to 32 weeks) neonates randomized to...

An effective preservation method and decreased rejection are essential for tracheal transplantation in the reconstruction of large airway defects. Our objective in the present study was to evaluate the antigenic properties of glycerin-preserved tracheal segments. Sixty-one tracheal segments (2.4 to 3.1 cm) were divided into three groups: autograft (N = 21), fresh allograft (N = 18) and glycerin...
