According to the invention, a slow setting bitumen-aggregate mix for cold paving is manufactured by a) preparing a cationic oil-in-water emulsion of bitumen in the presence of an emulsifier containing i) a tertiary polyamine selected from the group consisting of a di(C2-C3 alkylene)triamine, a tri(C2-C3 alkylene)tetraamine, a tetra(C2-C3 alkylene)pentaamine, a penta(C2-C3 alkylene)hexaamine, a hexa(C2 C3 alkylene)heptaamine or a mixture thereof, which amine compounds have only tertiary amine groups and contain one or two aliphatic groups with 8-22 carbon atoms, bound to a nitrogen atom, while the remaining nitrogen substituents are methyl groups and ii) an acid present in such an amount that the aqueous emulsion obtains a pH value from 1-6, preferably 1.5-5, and b) mixing the aqueous emulsion obtained with a solid aggregate. The present invention also comprises a tertiary polyamine selected from said group of tertiary polyamines or a salt thereof with an acid, a process for the production of said tertiary amine, as well as the use of the tertiary polyamine salt as an emulsifying or cohesion increasing agent.
摘要:
There is described a method for applying an aqueous solution to the internal walls of a reactor, before the start of the polymerization reaction of vinyl chloride and/or vinyl acetate, which aqueous solution contains a salt of an anti-scaling agent which comprises a product of condensation of an aldehyde, a phenolic compound and an aromatic carboxylic acid hydroxylated at the aromatic nucleus, wherein the pH-value of this aqueous solution is changed, during the application, to a pH-value of less than 5 and, preferably, in the range between 2.5 and 4.5.
摘要:
The invention relates to a process for the production of hydrogen peroxide comprising a liquid-liquid extraction step, said extraction step comprising contacting an organic feed solution containing hydrogen peroxide with an extraction solvent comprising less than about 30 wt % of water to achieve extraction of hydrogen peroxide to said extraction solvent and obtaining an extract containing hydrogen peroxide.
摘要:
Described are coccidia strains and microbiological cultures comprising such strains. The coccidia strains are selected for tolerance to one group of coccidiostatic drugs, sensitivity to a second group of coccidiostatic drugs, and decreased proliferative capacity. Also described are compositions and vaccines based on such coccidia strain.
摘要:
The invention relates to carbonated alkaline earth metal carboxylates that are neutral, meaning they have a base value of less than 10 mg KOH/g, and that are derived from a mixture of, preferably branched, optionally cyclic, C4-C40 alk(en)yl carboxylic acids and C6-C30 alkaryl or aralkyl carboxylic acids. Also a process to make such products is claimed, as well as the use of the products to stabilize PVC.
摘要:
The invention concerns a process for the production of chlorine dioxide, said process comprising the steps of continuously: feeding to a reactor an acid, alkali metal chlorate and a reducing agent; reacting the alkali metal chlorate with the acid and the reducing agent to form a product stream comprising chlorine dioxide, water and alkali metal salt of the acid; and, bringing the product stream from the reactor to an eductor and mixing it with a gaseous motive stream fed to the eductor and thereby forming a diluted product stream. The invention further concerns a production unit for the production of chlorine dioxide.
