The present invention is to provide a process for producing a tetrahydropyranyl-4-sulfonate which comprises allowing 3-buten-1-ol which is easily available to react with a formaldehyde compound and an organic sulfonic acid, and a process for producing a 4-aminotetrahydropyrane derivative, which is industrially useful, under mild conditions and by a simple and easy method to produce the 4-aminotetrahydropyrane derivative in high yield.

Processes for producing tetrahydropyranyl-4-sulfonates and 4-aminotetrahydropyran compounds

A monoclonal antibody which specifically binds okadaic acids and a process for producing the monoclonal antibody by culturing a cell strain capable of producing the antibody. The monoclonal antibody to okadaic acids labelled with an enzyme is useful for assaying okadaic acids.

There are disclosed a herbicidal composition containing, as an active ingredient, a phenoxyalkylamide derivative represented by the formula ##STR1## wherein X, n, Y, Z, R.sup.1, R.sup.2 and R.sup.3 have the same meanings as defined in the specification, and a method for controlling weeds by the use of the same. The herbicidal composition according to this invention shows a superior weed-killing activity by pre- and post-emergence treatment in soil.

Herbicidal composition containing a phenoxyalkylamide derivative and

There are presented new diphenyl ether derivatives having a substituent selected from a halogen atom, a trifluoromethyl group and a methoxy group at the 4-position in one phenyl moiety, having optionally also halo-substituents at the 2- and 6-positions, and having a nitro group at the 4'-position and a substituent selected from an unsubstituted or substituted (1,3-dioxorane-4-yl)methoxy group, an unsubstituted or substituted (1,3-dioxa-5-cyclohexyloxy) group and an alkyl- or (substituted)amino-sulfonyloxy group at the 3'-position in the other phenyl moiety. They exhibit improved herbicidal effects on various weeds without any adverse phytotoxic effect on crops, e.g. rice seedlings.

Diphenyl ether derivatives, process for preparing the same and

New diphenyl ether derivatives having one to three substituents selected from a halogen atom and a trifluoromethyl group at any optional one to three positions of the 2'-, 3'-, 4'-, 5'- and 6'-positions in one phenyl moiety and nitro group at the 4-position and unsubstituted or substituted aminosulfonyl group at the 3-position in another phenyl moiety. They have a superior herbicidal effect and can be prepared starting from a known 3-benzylmercapto compound through three steps.

Diphenyl ether derivatives and herbicidal compositions containing the
