  • Process for preparation of hydroperoxides
    Patent number: 6476276
    Abstract: A process for preparing hydroperoxides which comprises oxidizing hydrocarbon by a gas containing oxygen in the presence of a specific compound and converting them selectively to corresponding hydroperoxides. The specific compound is the compound that can capture radicals. The preferable example may be a compound selected from radicals of oxygen, nitrogen, phosphorus, sulfur, carbon or silicon or a compound that forms radicals of these in the reaction system. The present invention can be applied to oxidation of hydrocarbons including arylalkylhydrocarbons such as cumene, m-diisopropylbenzene, p-diisopropylbenzene, 1,3,5-triisopropylbenzene, isopropylnaphthalene, diisopropylnaphthalene, isopropylbiphenyl, diisopropylbiphenyl, etc.

  • Linear triene compound and copolymer
    Patent number: 6303727
    Abstract: A novel and useful linear triene compound represented by the following formula (1) is co-polymerized with an &agr;-olefin to obtain an ethylenically unsaturated copolymer which is superior in weather-ability, heat resitance and fastness to ozone, together with superior scorch stability and vulcanizability at high velocity in which R1, R2, R3, R4, R5 and R6 stand each, independently of each other, for hydrogen atom or an alkyl having 1-3 carbon atoms, R7 represents an alkyl having 1-3 carbon atoms and n is an integer of 0-5, with the proviso that each of R4s or of R5s may be identical with or different from each other, respectively, when n is 2 or greater.
