Dodecyl Lauryl Mercaptan

The reflux period required for complete reaction varies considerably with the structure of the halide. Some alkyl bromides require more than three hours. Alkyl chlorides frequently require sixteen hours and occasionally as much as twenty-four hours. [Pg.37]

This procedure is useful for the preparation of other mer-captans. The yields are of the same order. The boiling points are as follows [Pg.37]

While benzene is the most satisfactory solvent for this extraction, emulsions are sometimes produced when it is used for the extraction of other mercaptans. To obviate this difficulty the same amount of ether may be used, provided that the alcohol is first removed by distillation on a steam bath. [Pg.38]

6 If the ether extracts are not thoroughly dry, the mercaptan appears slightly cloudy on subsequent distillation. The checkers found that this cloudiness was frequently due to colloidal sulfur. The sulfur can be removed by shaking an ether solution of the cloudy product with bone black, then filtering and distilling. [Pg.38]

The odor of lauryl mercaptan is not disagreeable, and no unusual precautions need be taken in working with it. With lower-molecular-weight mercaptans a trap containing alkaline potassium permanganate solution will prevent the escape of unpleasant odors. [Pg.38]

The lower members have remarkably disagreeable odours, but the offensive odour diminishes with increasing carbon content until it almost disappears at about CioH2i SH, n-dodecyl (lauryl) mercaptan. [Pg.496]

Many isomers of dodecyl mercaptan are possible, and a variety of these occur in the technical material known as tert-dodecyl mercaptan, or lauryl mercaptan, or simply dodecyl mercaptan. [Pg.478]

We do not feel this explanation of the peculiarities of polymerization to be sufficient since re-combination reactions in the presence of primary radicals, formed from the regulator molecules, takes place in thermal polymerization of styrene as well. However, in this case the change of polymerization rate with increase of n-lauryl mercaptan concentration wasn t noted (4). In connection with this, we feel it expedient to consider styrene polymerization as a simpler system in the presence of widely used peroxide initiators (e.g., benzoyl peroxide (BP), t-butyl perbenzoate (TBPB), and regulators - n-lauryl mercaptan (NLM), n-butyl mercaptan (TMB), t-octyl mercaptan (TOM), t-decyl mercaptan (TDM), t-dodecyl mercaptan CTDDM), and t-pentadecyl mercaptan (TPDM)).

Mouran et al. [105] polymerized miniemulsions of methyl methacrylate with sodium lauryl sulfate as the surfactant and dodecyl mercaptan (DDM) as the costabilizer. The emulsions were of a droplet size range common to miniemulsions and exhibited long-term stability (of greater than three months). Results indicate that DDM retards Ostwald ripening and allows the production of stable miniemulsions. When these emulsions were initiated, particle formation occurred predominantly via monomer droplet nucleation. The rate of polymerization, monomer droplet size, polymer particle size, molecular weight of the polymer, and the effect of initiator concentration on the number of particles all varied systematically in ways that indicated predominant droplet nucleation.
