摘要:
Preparation of hydroxy-terminated conjugated diene polymers, particularly polybutadienes, by capping of organodilithium- and organopolylithium- terminated conjugated diene polymers or polybutadienes with lower alkylene oxide or epoxide capping agents in the presence of certain potentiating agents or catalysts exemplified particularly by small proportions of N,N,N.sup.1, N.sup.1 -tetramethylenediamine (TMEDA).
摘要:
Phenanthrenyl-butadienols, e.g., 2-(2-phenanthrenyl)-3,4pentadien-2-ol and their preparation are described. The compounds are useful as anti-inflammatories.
摘要:
Substituted and unsubstituted .alpha.-t-butyl-p-xylene-.alpha.,.alpha.'-diols, e.g., .alpha.-t-butyl-p-xylene-.alpha.,.alpha.'-diol, are prepared from the corresponding 4-pivaloyl-benzyl alcohols and are useful as hypolipidemic agents.
摘要:
Herbicidal compositions and methods in which an Alpha , Alpha diethynylbenzyl alcohol or an ester thereof is the herbicidally active ingredient, employed pre-emergently.
摘要:
THERE IS DISCLOSED A PROCESS FOR POLYMERIZING CONJUGATED DIENE MONOMERS TO FORM RELATIVELY LOW MOLECULAR WEIGHT POLYMERS. THE REACTION CAN BE CONDUCTED AT TEMPERATURES OF ABOUT 100*C. TO ABOUT 200*C. IN THE PRESENCE OF A HYDROGEN PROXIDE CATALYST AND A REACTION MEDIUM WHICH IS AN ESSENTIALLY WATER-INSOLUBLE, TRIHYDROCARBYL ORTHOPHOSPHATE ESTER. THE REACTION SYSTEM HAS AT LEAST TWO LIQUID PHASES FORMED BY THE MONOMER, CATALYST AND REACTION MEDIUM. TRICRESYL PHOSPHATE IS A PREFERRED MEDIUM.

IN THE PRESENCE OF A HYDROGEN PEROXIDE CATALYST AND A REACTION MEDIUM WHICH IS AN ESSENTIALLY WATER-INSOLUBLE, ALICYCLIC, MONOCYCLIC ALCOHOL OR KETONE HAVING AT LEAST SIX CARBON ATOMS IN A CARBOCYCLIC RING. THE REACTION SYSTEM HAS AT LEAST TWO LIQUID PHASES FORMED BY THE MONOMER, CATALYST AND REACTION MEDIUM. CYCLOHEXANOL IS A PREFERRED REACTION MEDIUM.
摘要:
Compounds of the general formula ARE DISCLOSED WHEREIN -R is selected from the group consisting of hydrogen, hydroxy, lower alkoxy of up to eight carbon atoms, lower alkyl of up to eight carbon atoms, and lower alkyl anilino of up to four carbon atoms; -R'' is selected from the group consisting of alkyl and alkenyl of up to 20 carbon atoms, cycloalkyl lower alkyl of up to three carbon atoms in the alkyl portion, adamantyl, pyridyl, furyl, lower alkyl carboxylic acids and their alkali metal salts, esters and carbamates; and R'''' and R'''''' are selected from the group consisting of lower alkyl of up to three carbon atoms. These compounds exhibit estrogenic properties and when given in a single subcutaneous dose have long acting effects in the suppression of animal reproduction.
