Hydrogenation

Robinson Brothers offers extensive know-how and expertise in large scale catalytic hydrogenation processes. Robinson Brothers dedicated hydrogenation facilities include an extensive array of specially designed pressure autoclave reactors ranging from R&D to large scale, which incorporate the latest computer controlled operating systems. Manufacturing capabilities include: Large scale hydrogenation autoclave reactors from 900L to 2,250L fabricated in...

Amination

Robinson Brothers routinely conducts reductive amination reactions to produce a wide range of speciality amine products and intermediates. Robinson Brothers is capable of performing reactions of an aliphatic or aromatic aldehyde, typically benzaldehydes, with a wide variety of alkyl amines to form an intermediate imine. This is subsequently reduced by catalytic hydrogenation to yield the amine with the product being distilled to required product specification. The reductive amination...

Amidation

Robinson Brothers is capable of handling anhydrous Ammonia and anhydrous alkylamines (e.g Methylamine) for animation reactions. Our puposely built chemical manufacturing plants allow anhydrous Ammonia and anyhydrous alkylamines to be fed into reactors, which are equipped with evaporator equipment allowing these reactants to be used in the gaseous phase. This can then be used for various amidation chemistries to yield amides and lower alkyl amides from e.g. carboxylic acids, acid...

Carbon Disulfide

Robinson Brothers has been involved in Carbon disulfide chemistry since manufacturing rubber accelerators in the 1930's. Today, Carbon disulfide is used as a versatile reagent for the manufacture of thiazoles, xanthates, thiocarbamates and thiuram disulfides for use in such diverse applications such as: pharmaceutical, veterinary, photographic, effluent treatment and rubber goods.  At Robinson Brothers, Carbon disulfide chemistries are carried out in our...

Chlorosulfonation

Robinson Brothers has the ability to handle Chlorosulfonic acid. Our production plants are equipped with a variety of reactor capacities to support manufacturing projects. Robinson Brothers can conduct chlorosulfonation reactions at an intermediate scale – manufacturing kilograms to tonne quantities at our UK chemical manufacturing site. All processes undergo rigorous safety testing and reaction hazard screening evaluations. Robinson Brothers has a dedicated in-house Process...

Dehydrogenation

Robinson Brothers offers many years of experience with dehydrogenation reactions. Robinson Brothers experience in catalytic hydrogenations has aided us in catalyst optimisation for dehydrogenation reactions. We have established intellectual know-how for dehydrogenation over a precious metal catalyst. Robinson Brothers UK chemical manufacturing site includes 9,000L glass-lined reactors with a double turbine agitator, specifically designed to degas. The dehydrogenation reactor has a...

Esterification

Robinson Brothers has a long history in the manufacture of Mercaptocarboxylic acid derivatives, particularly the esters of 2-Mercaptoacetic acid (Thioglycolic acid) and 3-Mercaptopropionic acid. Robinson Brothers is capable of manufacturing esters derived from a wide range of alcohols. We have particular know-how and expertise in manufacturing esters from low molecular weight, short chain length alcohols (including Methanol) to derive methylesters. Our UK chemical manufacturing site...

Heterocyclic Chemistry

Heterocyclic compounds represent the largest and most varied class of fine chemicals.  For the heterocycles of the most common elements of Oxygen, Nitrogen and Sulfur, the possible permutations for any given ring structure are incredibly numerous. They are important in many biological systems and processes, as such it is not surprising that they find wide application in pharmaceutical, agrochemical, aroma, food and beverage industries. Having a long tradition in the chemistries of...

Methylation

Robinson Brothers has the ability to handle Methyliodide to perform methylation chemistry. Robinson Brothers has experience in forming typical O-methylations and N-methylations, and more particularly, S-methylation reactions where Methyliodide offers some regioselectivity. We also perform N-methylation reactions using the Leuckart and Eschweiler-Clarke reactions. Robinson Brothers has bespoke containment facilities to handle a wide range of challenging materials on-site, such...

Oxidation

Robinson Brothers has a long history of performing oxidation chemistry. This continues to be a key strength in our core competences. Robinson Brothers inherent ability to handle Sulfur containing species and highly hazardous reagents safely, in compliance with regulation, has lent itself to further downstream chemistries such as oxidation. The following oxidation systems are currently used at Robinson Brothers: Hydrogen peroxide, H2O2 Sodium hypochlorite, NaOCl Sodium hypobromite,...

Thiolation

Robinson Brothers is equipped for the manufacture and application of organosulfur chemicals. Robinson Brothers is capable of performing numerous examples of thiolations for the preparation of alkyl and aryl mercaptans and thiols (R-SH). Our knowledge in thiolation chemistry stems back from early beginnings in the manufacture of Mercaptocarboxylic acids e.g. Thioglycolic acid and gas odorising materials e.g. Tetrahydrothiophene.  We are able to use and apply a wide variety of...
