Alkyl lactyllactate and alkoxylated alkyl lactyllactate compounds that are useful as solvents in a variety of applications are disclosed. The compounds are derived from a hydroxyl containing compound and a lactide or lactic acid source that has a specific chirality. The alkyl lactyllactate and alkoxylated alkyl lactyllactate compounds are particularly suitable for use as solvents in applications requiring cold tolerance performance without inclusion of additional volatile components.
摘要:
Provided are alkyl lactyllactate compositions that can be prepared from (1) lactide or alternatively lactic acid, and (2) a hydroxyl containing compound such as an alcohol, preferably a fatty alcohol or an alkoxylated alcohol, with (3) an acid catalyst. Preferably, the fatty alcohol contains from about 6 to 18 carbon atoms, such as lauryl alcohol. The alkyl lactyllactates can be used as surfactants, emulsifiers, skin feel agents, film formers, thickeners, rheological modifiers, etc., for personal care and other application areas. Compositions containing at least one alkyl lactyllactate are also provided. The compositions can further contain at least one surfactant.

摘要:
An apparatus having a frame adapted for earth traversing movement in a direction of travel and having portions laterally positionable with respect to the direction of travel, a work implement pivotally mounted on the laterally positionable portion of the frame for motion therewith relative to a predetermined axis through a range of selected operative positions, and a device for securing the work implement relative to the predetermined axis in a selected one of the operative positions for operation during movement of the frame along the path of travel.
摘要:
A rig for bait casting sandshrimp tails, and method for using the rig. A fish hook is attached to a forward end of fishing line leader. The forward end of a longitudinally elongated bait threader is attached to a rear end of the leader. A buoyant, bowling-pin-shaped, bobber is slidably mounted on the leader between the hook and threader. The rear end of the threader is pointed. In use, the pointed end of the threader is inserted longitudinally through a sandshrimp tail. The tail is moved forward over and past the threader, thence forward along the leader and onto the bobber so as to substantially enclose and surround the bobber. The rear end of the threader is then attached to a double swivel that is coupled to a weight and a fishing line.

An apparatus having a frame adapted for earth traversing movement in a direction of travel and having a portion laterally positionable with respect to the direction of travel, a work assembly pivotally mounted on the laterally positionable portion of the frame for movement therewith, and an arm interconnecting the work assembly and the frame to pivot the work assembly through a plurality of positions relative to the direction of travel as the portion of the frame is laterally positioned.
摘要:
Unsaturated alcohol compositions are obtained by reducing a metathesis-derived hydrocarbyl unsaturated ester. Also disclosed is a process for preparing an unsaturated alcohol composition, where a metathesis derived hydrocarbyl carbonyl compound is reacted in the presence of a silane compound, an organic solvent, and a catalyst system prepared from a metallic complex and a reducing agent. This mixture is then hydrolyzed with a metallic base, and then mixed with organic solvent. The resultant mixture is then separated, washed, dried, and/or purified to produce the unsaturated alcohol composition. The unsaturated alcohol derivatives are useful in many end-use applications, including, for example, lubricants, functional fluids, fuels, functional additives for such lubricants, functional fluids and fuels, plasticizers, asphalt additives, friction reducing agents, plastics, and adhesives.

Sulfonylethyl and thioethyl phosphorodiamidates, their preparation and intermediates in their preparation, formulations containing them, and their pharmaceutical use. The compounds are useful for treating cancer, alone and in combination with other anticancer therapies.
摘要:
Methods for preparing (S)-N-tert-butyl-1,2,3,4-tetrahydro-3-isoquinoline-carboxamide ("tic-c"), and converting tic-c to (S)-decahydroisoquinoline-3-carboxylic acid t-butylamide ("tic-d") are disclosed. The initial step in the formation of tic-c involves the phosgenation of a substituted tetrahydroisoquinoline to form an N-carboxy anhydride. Tic-d is used as an intermediate in the synthesis of known compounds having pharmaceutical activity.
