Abstract: A process for making alkyl 6-aminocaproate by hydroformylating 3-pentenenitrile to produce 3-, 4-, and 5-formylvaleronitrile (FVN mixture), converting the FVN mixture to alkyl 3-, 4-, and 5-cyanovalerate by either oxidative esterification of the FVN mixture or oxidation of the FVN mixture followed by esterification; isolating alkyl 5-cyanovalerate; and hydrogenating the alkyl 5-cyanovalerate to produce alkyl 6-aminocaproate. The resulting alkyl 6-aminocaproate can be cyclized to produce caprolactam.

Abstract: Commercially acceptable spandex can be prepared with greater efficiency, improved consistency and at lower costs from a high-solids content polyurethaneurea polymer solution. The polyurethaneurea is prepared using a combination of 4, 4'-MDI and 2,4'-MDI, and an amount of chain extenders and chain terminators such that the polymer solution, prior to spinning, is highly soluble and has an appropriate pre-spun IV and primary amine content.

Abstract: A method for recovering hexamethylene diamine (HMD) from a mixture (18) comprising HMD, 6-aminocapronitrile (ACN) tetrahydroazepine (THA), and ADN comprising: (a) introducing the mixture into a distillation column (20) capable of separating as a group the HMD, ACN and at least a portion of the THA from the ADN, while minimizing the isomerization of the ADN into CPI; and (b) introducing the HMD, ACN and at least a portion of the THA into a distillation column (26) capable of separating the HMD from the ACN in such a way that the THA separates along with the ACN.

Abstract: The invention provides an unwinder comprising: a frame; a fiber package holder affixed to said frame holding a package (10) of iber about a rational axis such that at least one fiber can unwind from said fiber package (0) in a direction defining an acute angle with the rational axis of the fiber package; a driven take-off roll (30) for unwinding fiber from the fiber package at a predetermined take-off rate; a first fiber guide (20) for directing fiber unwound from the fiber package (10), said first fiber guide positioned on said frame such that a distance (d) from the first fiber guide to the end of the fiber package (10) facing said first fiber guide, measured on the line defined by the rotational axis of the fiber package, is controlled in dependency of the level of tack exhibited by the fiber and an angle υ, defined by the intersection of imaginary lines corresponding, respectively, to the rotational axis of the package and the central axis of the fiber guide inlet orifice that is controlled in dependency of the level of tack exhibited by the fiber. The invention further provides a method for unwinding fiber.
