This technology affords more than 3 billion kilograms per year, and the economics have been optimized. [10] [11] Nevertheless, the ACH route coproduces substantial amounts of ammonium sulfate: roughly 1.1 kg/(kg MMA). The ammonium sulfate can be converted to diammonium sulfate, which is a common fertilizer.
Food plot in Germany. A food plot is a planted area set aside to act as a supplementary food source for wildlife. The term was coined by the U.S. hunting and outdoor industries and food plots are most commonly planted for game species. Food plot crops generally consist of but are not limited to legumes (clovers, alfalfa, beans, etc.), grains ...
Methyl acrylate is an organic compound, more accurately the methyl ester of acrylic acid.It is a colourless liquid with a characteristic acrid odor. It is mainly produced to make acrylate fiber, which is used to weave synthetic carpets. [6]
Methacrylic acid, abbreviated MAA, is an organic compound with the formula CH 2 =C(CH 3)CO 2 H. This colorless, viscous liquid is a carboxylic acid with an acrid unpleasant odor.
A significant part of the energy cost of industrial food production arises from the packaging and shipping of products to the increasingly urban consumer base. [6] The energy costs, pesticide use, and widespread erosion implicit in many forms of industrial food production have led to concerns about its long-term sustainability as a pattern of ...
It is a synthetic acrylate polymer derived from methyl acrylate monomer. The polymers are colorless. This homopolymer is far less important than copolymers derived from methyl acrylate and other monomers. PMA is softer than polymethyl methacrylate (PMMA), [1] It is tough, leathery, and flexible. [2]
The degree of polymerization, or DP, is the number of monomeric units in a macromolecule or polymer or oligomer molecule. [1] [2] [3]For a homopolymer, there is only one type of monomeric unit and the number-average degree of polymerization is given by ¯ ¯ = ¯, where ¯ is the number-average molecular weight and is the molecular weight of the monomer unit.
Despite hype rosier than practice, real recycling of polyolefins has been insufficient in the decades since they became ubiquitous, because of challenging economics. [22] Polyolefin waste can potentially be converted into many different products, including pure polymers, naphtha, clean fuels, or monomers, [ 23 ] but only to the extent that ...
