摘要:
Cyclopropanecarboxylic acid esters represented by the formula, WHEREIN R1 represents hydrogen or methyl; R2 represents methyl, 2-methyl-1-propenyl or 2-methoxy-carbonyl-1-propenyl when R1 is hydrogen and R2 represents methyl when R1 is methyl; R3 represents hydrogen or methyl; and R4 represents a lower alkylene radical containing or not containing oxygen or sulfur atom in its carbon chain, the alkylene having up to four carbon atoms, which may be useful as insecticides having high insecticidal effects and low toxicity to mammals.
WHEREIN R IS SEC-BUTYL OR TERT-BUTYL, WHICH IS PREPARED BY REACTING A HYDROXYL COMPOUND OF THE FORMULA:
2-(H3C-),5-R-PHENOL
WHEREIN R IS AS DEFINED ABOVE WITH PHOSGENE AND THEN REACTING THE RESULTANT CARBONYL CHLORIDE COMPOUND WITH METHYLAMINE OR BY REACTING THE SAID HYDROXYL COMPOUND WITH METHYL SIOCYANATE. THE CARBAMATE COMPOUND IS USEFUL AS AN INSECTICIDAL AGENT OF HIGH SAFETY.
摘要:
A gasket is prepared in a bottle cap by reacting in the bottle cap a first component containing a polyol having 2 or 3 hydroxyl functional groups in one molecule and a second component containing a polymethylene polyphenylisocyanate, preferably a quasi-prepolymer of a polymethylene polyphenylisocyanate having an isocyanate equivalent of not more than 300 until a cured substantially non-porous polyurethane gasket is obtained. The thus obtained seaing gasket undergoes neither deformation, color change nor weight loss over a prolonged period of time and has no tackiness on its surface.
