Microsoft Office shared tools are software components that are (or were) included in all Microsoft Office products.

Delve

Office Delve allows Office 365 users to search and manage their emails, meetings, contacts, social networks and documents stored on OneDrive or Sites in Office 365. Delve uses machine learning and artificial intelligence to try to show the most relevant people and content. In April 2015 Microsoft launched a mobile version of Office Delve in the App Store and Google Play for users with an Office 365 subscription.

Equation Editor

Equation Editor is a formula editor developed by Design Science that allows users to construct math and science equations in a WYSIWYG environment, and is included in Microsoft Office and several other commercial applications. It is a simplified version of Design Science's MathType, evidenced with a dialog box enticing the user to upgrade to the full, paid version of the software. It can be used as a standalone program or it can also be used as an embedded object from within applications that support OLE. Its feature set has not changed significantly since its introduction in Word for Windows version 2.0.

Methylene diphenyl diisocyanate

Methylene diphenyl diisocyanate, most often abbreviated as MDI, is an aromatic diisocyanate. It exists in three isomers, 2,2'-MDI, 2,4'-MDI, and 4,4'-MDI, however, the 4,4' isomer is most widely used. This isomer is also known as Pure MDI. MDI reacts with polyols in the manufacture of polyurethane. It is the most produced diisocyanate, accounting for 61.3% of the global market in the year 2000.

Production

Total world production of MDI and polymeric MDI is over 5 million tonnes per year (Mt/a in 2011). The largest producer is Bayer followed closely by Yantai Wanhua. Other major producers are BASF, BorsodChem, Dow, Huntsman, Nippon Polyurethane Industry, OCI. All major producers of MDI are members of the International Isocyanate Institute, whose aim is the promotion of the safe handling of MDI and TDI in the workplace, community and environment.

The first step of the production of MDI is the reaction of aniline and formaldehyde, using hydrochloric acid as a catalyst to produce a diamine precursor under the chemical formulation:
