- Compounding method for dozine
-
The invention provides a compounding method for dozine. The method comprises the following steps: taking guanidine hydrochloride as an initial raw material to react with chlorododecane, thereby acquiring a midbody A; adding an alkali aqueous solution into the midbody A for reaction; adding glacial acetic acid for reaction; performing after-treatment, thereby acquiring a target product dozine. The compounding method is characterized by easily acquired raw materials, few reaction steps, mild reaction condition, simplicity in operation and higher yield and is an environment-friendly compounding method, so that the compounding method is suitable for large-scale industrial production and has wide application prospect and market potential.

- Use of alkylguanidines as cationic emulsifiers
-
Emulsions comprising cationic emulsifiers and optionally coemulsifiers, optionally customary auxiliaries and additives, wherein the cationic emulsifiers used are at least one compound of the general formula (I) in which R1, R2, independently of the other, is at least one radical chosen from the group H, and/or an optionally branched, optionally multiple bond-containing hydrocarbon radical, a hydroxyalkyl, alkoxy, carboxyalkyl radical, an aminoalkyl, alkylaminoalkyl, amidoalkyl, alkylamidoalkyl radical, a homo- or heterocyclic, optionally substituted aliphatic or aromatic hydrocarbon radical having 1 to 60 carbon atoms, preferably 1 to 30 carbon atoms, in particular 12 to 18 carbon atoms, with the proviso that the sum of the carbon atoms from R1+R2 is at least 12 and X? is a salt-forming anion or the hydroxyl anion are provided.

- Soluble polymer based matrix for chemically active water insoluble components
-
This invention relates to a water soluble matrix composition comprising an anionic surfactant, a C6 to C18 alkyl pyrrolidone, urea and a water insoluble copolymer of vinyl pyrrolidone with not more than 50 wt. % of a comonomer selected from the group of an α-olefin, vinyl acetate, an acrylic or methacrylic acid ester and methacrylamide as a free flowing particulate solid which matrix is suitably mixed with a water insoluble, chemically active component, such as an agrochemical, to provide a clear sprayable film forming emulsion, such as a non-leachable film on a plant or other substrate surface. The invention also relates to the method of preparing the matrix and to the incorporation of an agrochemical concentrate and plant spray composition.

- Use of phosphoric esters as crystallization inhibitors
-
A new process for preventing the crystallization of certain azole derivatives in the spray equipment upon spraying mixtures containing A) certain azole derivatives which have a tendency to crystallize and B) if appropriate one or more other active compounds and additives, which process comprises adding at least one phosphoric ester of the formula STR1 in which R1 represents alkyl having 2 to 18 carbon atoms and R2 and R3 independently of one another represent alkyl having 2 to 12 carbon atoms, to the spray mixture before spraying.

- Preservative for aqueous products and systems
-
An antimicrobial composition for preserving products or systems containing an aqueous phase comprising from 10 to 60% by weight or tert.-butyl hydroperoxide, from 3 to 50% by weight of a monophenylglycol ether of formulas I or II herein, and the remainder a diluent which is water, an organic solvent or a mixture of water and organic solvent; and a method of use of the antimicrobial composition. The antimicrobial composition may additionally include up to about 20% by weight of a biocide selected from certain non-halogenated phenols, certain heterocyclic compounds and guanidine, phthalimide and urea derivatives.
